CVE-2014-8117

Updated file packages fix security vulnerabilities:

Thomas Jarosch of Intra2net AG reported that using the file command on a specially-crafted ELF binary could lead to a denial of service due to uncontrolled resource consumption (CVE-2014-8116).

Updated php and libgd packages fix security vulnerabilities:

Double free vulnerability in the zend_ts_hash_graceful_destroy function in zend_ts_hash.c in the Zend Engine in PHP before 5.5.21 allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors (CVE-2014-9425).

sapi/cgi/cgi_main.c in the CGI component in PHP before 5.5.21, when mmap is used to read a .php file, does not properly consider the mapping's length during processing of an invalid file that begins with a # character and lacks a newline character, which causes an out-of-bounds read and might allow remote attackers to obtain sensitive information from php-cgi process memory by leveraging the ability to upload a .php file or trigger unexpected code execution if a valid PHP script is present in memory locations adjacent to the mapping (CVE-2014-9427).

Use after free vulnerability in unserialize() in PHP before 5.5.21 (CVE-2015-0231).

Free called on an uninitialized pointer in php-exif in PHP before 5.5.21 (CVE-2015-0232).

The readelf.c source file has been removed from PHP's bundled copy of file's libmagic, eliminating exposure to denial of service issues in ELF file parsing such as CVE-2014-8116, CVE-2014-8117, CVE-2014-9620 and CVE-2014-9621 in PHP's fileinfo module.

A buffer read overflow in gd_gif_in.c in the php#68601 bug referenced in the PHP 5.5.21 ChangeLog has been fixed in the libgd package.

The php package has been updated to version 5.5.21 to fix these issues and other bugs. Please see the upstream ChangeLog for more information.

These are all security issues fixed in the file-5.29-2.1 package on the GA media of openSUSE Tumbleweed.

The GNU file utility was updated to version 5.22.

Security issues fixed:

• CVE-2014-9621: The ELF parser in file allowed remote attackers to cause a denial of service via a long string. (bsc#913650)
• CVE-2014-9620: The ELF parser in file allowed remote attackers to cause a denial of service via a large number of notes. (bsc#913651)
• CVE-2014-9653: readelf.c in file did not consider that pread calls sometimes read only a subset of the available data, which allows remote attackers to cause a denial of service (uninitialized memory access) or possibly have unspecified other impact via a crafted ELF file. (bsc#917152)
• CVE-2014-8116: The ELF parser (readelf.c) in file allowed remote attackers to cause a denial of service (CPU consumption or crash) via a large number of (1) program or (2) section headers or (3) invalid capabilities. (bsc#910253)
• CVE-2014-8117: softmagic.c in file did not properly limit recursion, which allowed remote attackers to cause a denial of service (CPU consumption or crash) via unspecified vectors. (bsc#910253)

Version update to file version 5.22

• add indirect relative for TIFF/Exif
• restructure elf note printing to avoid repeated messages
• add note limit, suggested by Alexander Cherepanov
• Bail out on partial pread()'s (Alexander Cherepanov)
• Fix incorrect bounds check in file_printable (Alexander Cherepanov)
• PR/405: ignore SIGPIPE from uncompress programs
• change printable -> file_printable and use it in more places for safety
• in ELF, instead of '(uses dynamic libraries)' when PT_INTERP is present print the interpreter name.

Version update to file version 5.21

• there was an incorrect free in magic_load_buffers()
• there was an out of bounds read for some pascal strings
• there was a memory leak in magic lists
• don't interpret strings printed from files using the current locale, convert them to ascii format first.
• there was an out of bounds read in elf note reads

Update to file version 5.20

• recognize encrypted CDF documents
• add magic_load_buffers from Brooks Davis
• add thumbs.db support

Additional non-security bug fixes:

• Fixed a memory corruption during rpmbuild (bsc#1063269)
• Backport of a fix for an increased printable string length as found in file 5.30 (bsc#996511)
• file command throws 'Composite Document File V2 Document, corrupt: Can't read SSAT' error against excel 97/2003 file format. (bsc#1009966)

softmagic.c in file before 5.21 does not properly limit recursion, which allows remote attackers to cause a denial of service (CPU consumption or crash) via unspecified vectors.

Francisco Alonso discovered that file incorrectly handled certain ELF files. An attacker could use this issue to cause file to crash, resulting in a denial of service. (CVE-2014-3710)

Thomas Jarosch discovered that file incorrectly handled certain ELF files. An attacker could use this issue to cause file to hang or crash, resulting in a denial of service. (CVE-2014-8116)

Thomas Jarosch discovered that file incorrectly limited recursion. An attacker could use this issue to cause file to hang or crash, resulting in a denial of service. (CVE-2014-8117)

Thomas Jarosch discovered that PHP incorrectly limited recursion in the fileinfo extension. A remote attacker could possibly use this issue to cause PHP to consume resources or crash, resulting in a denial of service. (CVE-2014-8117)

S. Paraschoudis discovered that PHP incorrectly handled memory in the enchant binding. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2014-9705)

Taoguang Chen discovered that PHP incorrectly handled unserializing objects. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-0273)
