Mandriva Linux Security Advisory : php (MDVSA-2009:324)

High Nessus Plugin ID 43043

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 7.4

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

Multiple vulnerabilities was discovered and corrected in php :

The dba_replace function in PHP 5.2.6 and 4.x allows context-dependent attackers to cause a denial of service (file truncation) via a key with the NULL byte. NOTE: this might only be a vulnerability in limited circumstances in which the attacker can modify or add database entries but does not have permissions to truncate the file (CVE-2008-7068).

The JSON_parser function (ext/json/JSON_parser.c) in PHP 5.2.x before 5.2.9 allows remote attackers to cause a denial of service (segmentation fault) via a malformed string to the json_decode API function (CVE-2009-1271).

- Fixed upstream bug #48378 (exif_read_data() segfaults on certain corrupted .jpeg files) (CVE-2009-2687).

The php_openssl_apply_verification_policy function in PHP before 5.2.11 does not properly perform certificate validation, which has unknown impact and attack vectors, probably related to an ability to spoof certificates (CVE-2009-3291).

Unspecified vulnerability in PHP before 5.2.11 has unknown impact and attack vectors related to missing sanity checks around exif processing. (CVE-2009-3292)

Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect sanity check for the color index. (CVE-2009-3293)

The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.0, and the GD Graphics Library 2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability than CVE-2009-3293. NOTE: some of these details are obtained from third-party information (CVE-2009-3546).

The tempnam function in ext/standard/file.c in PHP 5.2.11 and earlier, and 5.3.x before 5.3.1, allows context-dependent attackers to bypass safe_mode restrictions, and create files in group-writable or world-writable directories, via the dir and prefix arguments (CVE-2009-3557).

The posix_mkfifo function in ext/posix/posix.c in PHP 5.2.11 and earlier, and 5.3.x before 5.3.1, allows context-dependent attackers to bypass open_basedir restrictions, and create FIFO files, via the pathname and mode arguments, as demonstrated by creating a .htaccess file (CVE-2009-3558).

PHP 5.2.11, and 5.3.x before 5.3.1, does not restrict the number of temporary files created when handling a multipart/form-data POST request, which allows remote attackers to cause a denial of service (resource exhaustion), and makes it easier for remote attackers to exploit local file inclusion vulnerabilities, via multiple requests, related to lack of support for the max_file_uploads directive (CVE-2009-4017).

The proc_open function in ext/standard/proc_open.c in PHP before 5.2.11 and 5.3.x before 5.3.1 does not enforce the (1) safe_mode_allowed_env_vars and (2) safe_mode_protected_env_vars directives, which allows context-dependent attackers to execute programs with an arbitrary environment via the env parameter, as demonstrated by a crafted value of the LD_LIBRARY_PATH environment variable (CVE-2009-4018).

The dba_replace function in PHP 5.2.6 and 4.x allows context-dependent attackers to cause a denial of service (file truncation) via a key with the NULL byte. NOTE: this might only be a vulnerability in limited circumstances in which the attacker can modify or add database entries but does not have permissions to truncate the file (CVE-2008-7068).

The php_openssl_apply_verification_policy function in PHP before 5.2.11 does not properly perform certificate validation, which has unknown impact and attack vectors, probably related to an ability to spoof certificates (CVE-2009-3291).

Unspecified vulnerability in PHP before 5.2.11 has unknown impact and attack vectors related to missing sanity checks around exif processing. (CVE-2009-3292)

Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect sanity check for the color index. (CVE-2009-3293). However in Mandriva we don't use the bundled libgd source in php per default, there is a unsupported package in contrib named php-gd-bundled that eventually will get updated to pickup these fixes.

The php-suhosin package has been upgraded to 0.9.22 which has better support for apache vhosts.

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers

This update provides a solution to these vulnerabilities.

Solution

Update the affected packages.
