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."

Multiple issues have been fixed in php5 :

  - php_openssl_apply_verification_policy() fails to verify     certificate. (CVE-2009-3291)

  - 'missing sainity checks around exif'. (CVE-2009-3292)

  - unspecified vulnerability in the     imagecolortransparent(). (CVE-2009-3293)

  - denial of service in exif module (CVE-2009-2687)     Additionally we fixed :

  - xmlparse was broken

  - read_exif_data() only returns the first letter of UTF-16     strings

Multiple vulnerabilities was discovered and corrected in php :

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.

This update provides a solution to these vulnerabilities.

The remote host is affected by the vulnerability described in GLSA-201001-03 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the     CVE identifiers referenced below and the associated PHP release notes     for details.
  Impact :

    A context-dependent attacker could execute arbitrary code via a     specially crafted string containing an HTML entity when the mbstring     extension is enabled. Furthermore a remote attacker could execute     arbitrary code via a specially crafted GD graphics file.
    A remote attacker could also cause a Denial of Service via a malformed     string passed to the json_decode() function, via a specially crafted     ZIP file passed to the php_zip_make_relative_path() function, via a     malformed JPEG image passed to the exif_read_data() function, or via     temporary file exhaustion. It is also possible for an attacker to spoof     certificates, bypass various safe_mode and open_basedir restrictions     when certain criteria are met, perform Cross-site scripting attacks,     more easily perform SQL injection attacks, manipulate settings of other     virtual hosts on the same server via a malicious .htaccess entry when     running on Apache, disclose memory portions, and write arbitrary files     via a specially crafted ZIP archive. Some vulnerabilities with unknown     impact and attack vectors have been reported as well.
  Workaround :

    There is no known workaround at this time.

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).
