Mandriva Linux Security Advisory 2008-126
Posted Jul 10, 2008
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory - PHP 5.2.1 would allow context-dependent attackers to read portions of heap memory by executing certain scripts with a serialized data input string beginning with 'S:', which did not properly track the number of input bytes being processed. A vulnerability in the chunk_split() function in PHP prior to 5.2.4 has unknown impact and attack vectors, related to an incorrect size calculation. The htmlentities() and htmlspecialchars() functions in PHP prior to 5.2.5 accepted partial multibyte sequences, which has unknown impact and attack vectors. The output_add_rewrite_var() function in PHP prior to 5.2.5 rewrites local forms in which the ACTION attribute references a non-local URL, which could allow a remote attacker to obtain potentially sensitive information by reading the requests for this URL. The escapeshellcmd() API function in PHP prior to 5.2.6 has unknown impact and context-dependent attack vectors related to incomplete multibyte characters. Weaknesses in the GENERATE_SEED macro in PHP prior to 4.4.8 and 5.2.5 were discovered that could produce a zero seed in rare circumstances on 32bit systems and generations a portion of zero bits during conversion due to insufficient precision on 64bit systems. CVE-2008-2108). The IMAP module in PHP uses obsolete API calls that allow context-dependent attackers to cause a denial of service (crash) via a long IMAP request.

Gentoo Linux Security Advisory 200710-2
Posted Oct 9, 2007
Authored by Gentoo | Site security.gentoo.org

Gentoo Linux Security Advisory GLSA 200710-02 - Several vulnerabilities were found in PHP. Mattias Bengtsson and Philip Olausson reported integer overflows in the gdImageCreate() and gdImageCreateTrueColor() functions of the GD library which can cause heap-based buffer overflows. Gerhard Wagner discovered an integer overflow in the chunk_split() function that can lead to a heap-based buffer overflow. Its incomplete fix caused incorrect buffer size calculation due to precision loss, also resulting in a possible heap-based buffer overflow. A buffer overflow in the sqlite_decode_binary() of the SQLite extension found by Stefan Esser that was addressed in PHP 5.2.1 was not fixed correctly. Versions less than 5.2.4_p20070914-r2 are affected.
