Mandriva Linux Security Advisory - php-cgi in PHP prior to 5.2.6 does not properly calculate the length of PATH_TRANSLATED, which has unknown impact and attack vectors. 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. 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. In addition, the updated packages provide a number of bug fixes. The updated packages have been patched to correct these issues.

Mandriva Linux Security Advisory - 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. php-cgi in PHP prior to 5.2.6 does not properly calculate the length of PATH_TRANSLATED, which has unknown impact and attack vectors. 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. 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. In addition, this update also corrects an issue with some float to string conversions.

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.

Debian Linux Security Advisory 1578-1
Posted May 20, 2008

Debian Security Advisory 1578-1 - Several vulnerabilities have been discovered in PHP version 4, a server-side, HTML-embedded scripting language. The session_start function allows remote attackers to insert arbitrary attributes into the session cookie via special characters in a cookie that is obtained from various parameters. A denial of service was possible through a malicious script abusing the glob() function. Certain maliciously constructed input to the wordwrap() function could lead to a denial of service attack. Large len values of the stspn() or strcspn() functions could allow an attacker to trigger integer overflows to expose memory or cause denial of service. The escapeshellcmd API function could be attacked via incomplete multibyte chars.

Debian Security Advisory 1572-1 - Several vulnerabilities have been discovered in PHP, a server-side, HTML-embedded scripting language. The glob function allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via an invalid value of the flags parameter. Integer overflow allows context-dependent attackers to cause a denial of service and possibly have other impact via a printf format parameter with a large width specifier. Stack-based buffer overflow in the FastCGI SAPI. The escapeshellcmd API function could be attacked via incomplete multibyte chars.
