These are all security issues fixed in the binutils-2.41-1.2 package on the GA media of openSUSE Tumbleweed.

This update for binutils fixes the following issues:

Update to version 2.41 [jsc#PED-5778]:

• The MIPS port now supports the Sony Interactive Entertainment Allegrex processor, used with the PlayStation Portable, which implements the MIPS II ISA along with a single-precision FPU and a few implementation-specific integer instructions.

• Objdump's --private option can now be used on PE format files to display the fields in the file header and section headers.

• New versioned release of libsframe: libsframe.so.1. This release introduces versioned symbols with version node name LIBSFRAME_1.0. This release also updates the ABI in an incompatible way: this includes removal of sframe_get_funcdesc_with_addr API, change in the behavior of sframe_fre_get_ra_offset and sframe_fre_get_fp_offset APIs.

• SFrame Version 2 is now the default (and only) format version supported by gas, ld, readelf and objdump.

• Add command-line option, --strip-section-headers, to objcopy and strip to remove ELF section header from ELF file.

• The RISC-V port now supports the following new standard extensions:

  • Zicond (conditional zero instructions)
  • Zfa (additional floating-point instructions)
  • Zvbb, Zvbc, Zvkg, Zvkned, Zvknh[ab], Zvksed, Zvksh, Zvkn, Zvknc, Zvkng, Zvks, Zvksc, Zvkg, Zvkt (vector crypto instructions)

• The RISC-V port now supports the following vendor-defined extensions:

  • XVentanaCondOps

• Add support for Intel FRED, LKGS and AMX-COMPLEX instructions.

• A new .insn directive is recognized by x86 gas.

• Add SME2 support to the AArch64 port.

• The linker now accepts a command line option of --remap-inputs <PATTERN>=<FILE> to relace any input file that matches <PATTERN> with <FILE>. In addition the option --remap-inputs-file=<FILE> can be used to specify a file containing any number of these remapping directives.

• The linker command line option --print-map-locals can be used to include local symbols in a linker map. (ELF targets only).

• For most ELF based targets, if the --enable-linker-version option is used then the version of the linker will be inserted as a string into the .comment section.

• The linker script syntax has a new command for output sections: ASCIZ 'string' This will insert a zero-terminated string at the current location.

• Add command-line option, -z nosectionheader, to omit ELF section header.

• Contains fixes for these non-CVEs (not security bugs per upstreams SECURITY.md):

This update for gdb fixes the following issues:

• Drop libdebuginfod1 BuildRequires/Recommends. The former isn't needed because there's a build requirement on libdebuginfod-devel already, which will pull the shared library. And the latter, because it's bogus since RPM auto generated dependency will take care of that requirement.

gdb was released in 13.2:

• This version of GDB includes the following changes and enhancements:

  • Support for the following new targets has been added in both GDB and GDBserver:

    * GNU/Linux/LoongArch (gdbserver) loongarch*-*-linux*
    * GNU/Linux/CSKY (gdbserver) csky*-*linux* 
    

  • The Windows native target now supports target async.

  • Floating-point support has now been added on LoongArch GNU/Linux.

  • New commands:

    * set print nibbles [on|off]
    * show print nibbles
    
    * This controls whether the 'print/t' command will display binary values in groups of four bits, known as 'nibbles'. The default is 'off'.
      Various styling-related commands. See the gdb/NEWS file for more details.
      Various maintenance commands. These are normally aimed at GDB experts or developers. See the gdb/NEWS file for more details. 
    

  • Python API improvements:

      * New Python API for instruction disassembly.
    
      * The new attribute 'locations' of gdb.Breakpoint returns a list of gdb.BreakpointLocation objects specifying the locations where the breakpoint is inserted into the debuggee.
      * New Python type gdb.BreakpointLocation.
      * New function gdb.format_address(ADDRESS, PROGSPACE, ARCHITECTURE) that formats ADDRESS as 'address '
      * New function gdb.current_language that returns the name of the current language. Unlike gdb.parameter('language'), this will never return 'auto'.
      * New function gdb.print_options that returns a dictionary of the prevailing print options, in the form accepted by gdb.Value.format_string.
      * New method gdb.Frame.language that returns the name of the frame's language.
      * gdb.Value.format_string now uses the format provided by 'print', if it is called during a 'print' or other similar operation.
      * gdb.Value.format_string now accepts the 'summary' keyword. This can be used to request a shorter representation of a value, the way that 'set print frame-arguments scalars' does.
      * The gdb.register_window_type method now restricts the set of acceptable window names. The first character of a window's name must start with a character in the set [a-zA-Z], every subsequent character of a window's name must be in the set [-_.a-zA-Z0-9]. 
    

  • GDB/MI changes:

     * MI version 1 is deprecated, and will be removed in GDB 14.
     * The async record stating the stopped reason 'breakpoint-hit' now contains an optional field locno. 
    

  • Miscellaneous improvements:

     * gdb now supports zstd compressed debug sections (ELFCOMPRESS_ZSTD) for ELF.
     * New convenience variable $_inferior_thread_count contains the number of live threads in the current inferior.
     * New convenience variables $_hit_bpnum and $_hit_locno, set to the breakpoint number and the breakpoint location number of the breakpoint last hit.
     * The 'info breakpoints' now displays enabled breakpoint locations of disabled breakpoints as in the 'y-' state.
     * The format of 'disassemble /r' and 'record instruction-history /r' has changed to match the layout of GNU objdump when disassembling.
    
     * A new format '/b' has been introduce to provide the old behavior of '/r'.
     * The TUI no longer styles the source and assembly code highlighted by the current position indicator by default. You can however re-enable styling using the new 'set style tui-current-position' command.
     * It is now possible to use the 'document' command to document user-defined commands.
     * Support for memory tag data for AArch64 MTE.

    * GNU/Linux/CSKY (gdbserver) csky*-*linux* 
    

  • The Windows native target now supports target async.

  • Floating-point support has now been added on LoongArch GNU/Linux.

  • New commands:

    * set print nibbles [on|off]
    * show print nibbles
    
    * This controls whether the 'print/t' command will display binary values in groups of four bits, known as 'nibbles'. The default is 'off'.
      Various styling-related commands. See the gdb/NEWS file for more details.
      Various maintenance commands. These are normally aimed at GDB experts or developers. See the gdb/NEWS file for more details. 
    

  • Python API improvements:

      * New Python API for instruction disassembly.
    
      * The new attribute 'locations' of gdb.Breakpoint returns a list of gdb.BreakpointLocation objects specifying the locations where the breakpoint is inserted into the debuggee.
      * New Python type gdb.BreakpointLocation.
      * New function gdb.format_address(ADDRESS, PROGSPACE, ARCHITECTURE) that formats ADDRESS as 'address '
      * New function gdb.current_language that returns the name of the current language. Unlike gdb.parameter('language'), this will never return 'auto'.
      * New function gdb.print_options that returns a dictionary of the prevailing print options, in the form accepted by gdb.Value.format_string.
      * New method gdb.Frame.language that returns the name of the frame's language.
      * gdb.Value.format_string now uses the format provided by 'print', if it is called during a 'print' or other similar operation.
      * gdb.Value.format_string now accepts the 'summary' keyword. This can be used to request a shorter representation of a value, the way that 'set print frame-arguments scalars' does.
      * The gdb.register_window_type method now restricts the set of acceptable window names. The first character of a window's name must start with a character in the set [a-zA-Z], every subsequent character of a window's name must be in the set [-_.a-zA-Z0-9]. 
    

  • GDB/MI changes:

     * MI version 1 is deprecated, and will be removed in GDB 14.
     * The async record stating the stopped reason 'breakpoint-hit' now contains an optional field locno. 
    

  • Miscellaneous improvements:

     * gdb now supports zstd compressed debug sections (ELFCOMPRESS_ZSTD) for ELF.
     * New convenience variable $_inferior_thread_count contains the number of live threads in the current inferior.
     * New convenience variables $_hit_bpnum and $_hit_locno, set to the breakpoint number and the breakpoint location number of the breakpoint last hit.
     * The 'info breakpoints' now displays enabled breakpoint locations of disabled breakpoints as in the 'y-' state.
     * The format of 'disassemble /r' and 'record instruction-history /r' has changed to match the layout of GNU objdump when disassembling.
    
     * A new format '/b' has been introduce to provide the old behavior of '/r'.
     * The TUI no longer styles the source and assembly code highlighted by the current position indicator by default. You can however re-enable styling using the new 'set style tui-current-position' command.
     * It is now possible to use the 'document' command to document user-defined commands.
     * Support for memory tag data for AArch64 MTE. 
    

  *…

This update for gdb fixes the following issues:

Mention changes in GDB 14:

• GDB now supports the AArch64 Scalable Matrix Extension 2 (SME2), which includes a new 512 bit lookup table register named ZT0.
• GDB now supports the AArch64 Scalable Matrix Extension (SME), which includes a new matrix register named ZA, a new thread register TPIDR2 and a new vector length register SVG (streaming vector granule). GDB also supports tracking ZA state across signal frames. Some features are still under development or are dependent on ABI specs that are still in alpha stage. For example, manual function calls with ZA state don't have any special handling, and tracking of SVG changes based on DWARF information is still not implemented, but there are plans to do so in the future.
• GDB now recognizes the NO_COLOR environment variable and disables styling according to the spec. See https://no-color.org/. Styling can be re-enabled with 'set style enabled on'.
• The AArch64 'org.gnu.gdb.aarch64.pauth' Pointer Authentication feature string has been deprecated in favor of the 'org.gnu.gdb.aarch64.pauth_v2' feature string.
• GDB now has some support for integer types larger than 64 bits.
• Multi-target feature configuration. GDB now supports the individual configuration of remote targets' feature sets. Based on the current selection of a target, the commands 'set remote <name>-packet (on|off|auto)' and 'show remote <name>-packet' can be used to configure a target's feature packet and to display its configuration, respectively.
• GDB has initial built-in support for the Debugger Adapter Protocol.
• For the break command, multiple uses of the 'thread' or 'task' keywords will now give an error instead of just using the thread or task id from the last instance of the keyword. E.g.: break foo thread 1 thread 2 will now give an error rather than using 'thread 2'.
• For the watch command, multiple uses of the 'task' keyword will now give an error instead of just using the task id from the last instance of the keyword. E.g.: watch my_var task 1 task 2 will now give an error rather than using 'task 2'. The 'thread' keyword already gave an error when used multiple times with the watch command, this remains unchanged.
• The 'set print elements' setting now helps when printing large arrays. If an array would otherwise exceed max-value-size, but 'print elements' is set such that the size of elements to print is less than or equal to 'max-value-size', GDB will now still print the array, however only 'max-value-size' worth of data will be added into the value history.
• For both the break and watch commands, it is now invalid to use both the 'thread' and 'task' keywords within the same command. For example the following commnds will now give an error: break foo thread 1 task 1 watch var thread 2 task 3
• The printf command now accepts a '%V' output format which will format an expression just as the 'print' command would. Print options can be placed withing '[...]' after the '%V' to modify how the value is printed. E.g: printf '%V', some_array printf '%V[-array-indexes on]', some_array will print the array without, or with array indexes included, just as the array would be printed by the 'print' command. This functionality is also available for dprintf when dprintf-style is 'gdb'.
• When the printf command requires a string to be fetched from the inferior, GDB now uses the existing 'max-value-size' setting to the limit the memory allocated within GDB. The default 'max-value-size' is 64k. To print longer strings you should increase 'max-value-size'.
• The Ada 2022 Enum_Rep and Enum_Val attributes are now supported.
• The Ada 2022 target name symbol ('@') is now supported by the Ada expression parser.
• The 'list' command now accepts '.' as an argument, which tells GDB to print the location around the point of execution…
