CVE-2024-53427

decNumberCopy in decNumber.c in jq through 1.7.1 does not properly consider that NaN is interpreted as numeric, which has a resultant stack-based buffer overflow and out-of-bounds write, as demonstrated by use of --slurp with subtraction, such as a filter of .-. when the input has a certain form of digit string with NaN (e.g., "1 NaN123" immediately followed by many more digits).

These are all security issues fixed in the jq-1.7.1-3.1 package on the GA media of openSUSE Tumbleweed.

Changes for jq:

Update to version 1.7.1:

• Make the default background color more suitable for bright backgrounds.
• Allow passing the inline jq script after --.
• Fix possible uninitialised value dereference if jq_init() fails
• Simplify paths/0 and paths/1.
• Reject U+001F in string literals.
• Remove unused nref accumulator in block_bind_library.
• Remove a bunch of unused variables, and useless assignments.
• main.c: Remove unused EXIT_STATUS_EXACT option.
• Actually use the number correctly casted from double to int as index.
• src/builtin.c: remove unnecessary jv_copy-s in type_error/type_error2.
• Remove undefined behavior caught by LLVM 10 UBSAN.
• Convert decnum to binary64 (double) instead of decimal64. This makes jq behave like the JSON specification suggests and more similar to other languages.
• Fix memory leaks on invalid input for ltrimstr/1 and rtrimstr/1.
• Fix memory leak on failed get for setpath/2.
• Fix nan from json parsing also for nans with payload that start with 'n'.
• Allow carriage return characters in comments.
• Generate links in the man page.
• Add extern C for C++.
• Make object key color configurable using JQ_COLORS environment variable.
• Change the default color of null to Bright Black.
• Respect NO_COLOR environment variable to disable color output.
• Improved --help output. Now mentions all options and nicer order.
• Fix multiple issues of exit code using --exit-code/-e option.
• Add --raw-output0 for NUL (zero byte) separated output.
• Fix assert crash and validate JSON for --jsonarg.
• Remove deprecated --argfile option.
• Use decimal number literals to preserve precision. Comparison operations respects precision but arithmetic operations might truncate.
• Adds new builtin pick(stream) to emit a projection of the input object or array.
• Adds new builtin…
