The strrchr function in PHP 5.2 before 5.2.14 allows context-dependent attackers to obtain sensitive information (memory contents) or trigger memory corruption by causing a userspace interruption of an internal function or handler.

Mateusz Kocielski, Marek Kroemeke and Filip Palian discovered that a stack-based buffer overflow existed in the socket_connect function's handling of long pathnames for AF_UNIX sockets. A remote attacker might be able to exploit this to execute arbitrary code; however, the default compiler options for affected releases should reduce the vulnerability to a denial of service. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-1938)

Krzysztof Kotowicz discovered that the PHP post handler function does not properly restrict filenames in multipart/form-data POST requests.
This may allow remote attackers to conduct absolute path traversal attacks and possibly create or overwrite arbitrary files. This issue affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-2202)

It was discovered that the crypt function for blowfish does not properly handle 8-bit characters. This could make it easier for an attacker to discover a cleartext password containing an 8-bit character that has a matching blowfish crypt value. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04.
(CVE-2011-2483)

It was discovered that PHP did not properly check the return values of the malloc(3), calloc(3) and realloc(3) library functions in multiple locations. This could allow an attacker to cause a denial of service via a NULL pointer dereference or possibly execute arbitrary code.
This issue affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-3182)

Maksymilian Arciemowicz discovered that PHP did not properly implement the error_log function. This could allow an attacker to cause a denial of service via an application crash. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10, Ubuntu 11.04 and Ubuntu 11.10. (CVE-2011-3267)

Maksymilian Arciemowicz discovered that the ZipArchive functions addGlob() and addPattern() did not properly check their flag arguments. This could allow a malicious script author to cause a denial of service via application crash. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10, Ubuntu 11.04 and Ubuntu 11.10.
(CVE-2011-1657)

It was discovered that the Xend opcode parser in PHP could be interrupted while handling the shift-left, shift-right, and bitwise-xor opcodes. This could allow a malicious script author to expose memory contents. This issue affected Ubuntu 10.04 LTS.
(CVE-2010-1914)

It was discovered that the strrchr function in PHP could be interrupted by a malicious script, allowing the exposure of memory contents. This issue affected Ubuntu 8.04 LTS. (CVE-2010-2484).

This is a maintenance and security update that upgrades php to 5.2.14 for CS4/MES5/2008.0/2009.0/2009.1.

Security Enhancements and Fixes in PHP 5.2.14 :

  - Rewrote var_export() to use smart_str rather than output     buffering, prevents data disclosure if a fatal error     occurs (CVE-2010-2531).

  - Fixed a possible interruption array leak in     strrchr().(CVE-2010-2484)

  - Fixed a possible interruption array leak in strchr(),     strstr(), substr(), chunk_split(), strtok(),     addcslashes(), str_repeat(), trim().

  - Fixed a possible memory corruption in substr_replace().

    - Fixed SplObjectStorage unserialization problems       (CVE-2010-2225).

    - Fixed a possible stack exaustion inside fnmatch().

    - Fixed a NULL pointer dereference when processing       invalid XML-RPC requests (Fixes CVE-2010-0397, bug       #51288).

  - Fixed handling of session variable serialization on     certain prefix characters.

  - Fixed a possible arbitrary memory access inside sqlite     extension. Reported by Mateusz Kocielski.

Additionally some of the third-party extensions has been upgraded and/or rebuilt for the new php version.

Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

  - An information disclosure vulnerability in var_export() when a fatal error occurs.

  - A resource destruction issue in shm_put_var().

  - A possible information leak because of an interruption of XOR operator.

  - A memory corruption issue caused by an unexpected call-time pass by reference and the following memory clobbering through callbacks.

  - A memory corruption issue in ArrayObject::uasort().

  - A memory corruption issue in parse_str().

  - A memory corruption issue in pack().

  - A memory corruption issue in substr_replace().

  - A memory corruption issue in addcslashes().

  - A stack exhaustion issue in fnmatch().

  - A buffer overflow vulnerability in the dechunking filter.

  - An arbitrary memory access issue in the sqlite extension.

  - A string format validation issue in the phar extension.

  - An unspecified issue relating to the handling of session variable serialization on certain prefix characters.

  - A NULL pointer dereference issue when processing invalid XML-RPC requests.

  - An unserialization issue in SplObjectStorage.

  - Buffer overflow vulnerabilities in mysqlnd_list_fields and mysqlnd_change_user.

  - Buffer overflows when handling error packets in mysqlnd.

Versions of PHP prior to 5.2.14, or 5.3.x prior to 5.3.3 are affected by the following vulnerabilities :

 - An information disclosure vulnerability in 'var_export()' when a fatal error occurs.
 - A resource destruction issue in 'shm_put_var()'.
 - A possible information leak because of an interruption of XOR operator.
 - A memory corruption issue caused by an unexpected call-time pass by reference and the following memory clobbering through callbacks.
 - A memory corruption issue in 'ArrayObject::uasort()'.
 - A memory corruption issue in 'parse_str()'.
 - A memory corruption issue in 'pack()'.
 - A memory corruption issue in 'substr_replace()'.
 - A memory corruption issue in 'addcslashes()'.
 - A stack exhaustion issue in 'fnmatch()'.
 - A buffer overflow vulnerability in the dechunking filter.
 - An arbitrary memory access issue in the sqlite extension.
 - A string format validation issue in the phar extension.
 - An unspecified issue relating to the handling of session variable serialization on certain prefix characters.
 - A NULL pointer dereference issue when processing invalid XML-RPC requests.
 - An unserialization issue in 'SplObjectStorage'.
 - Buffer overflow vulnerabilities in 'mysqlnd_list_fields' and 'mysqlnd_change_user'.
 - Buffer overflows when handling error packets in mysqlnd.
 - A flaw affects 'sqlite_single_query()' and 'sqlite_array_query()' methods included in the 'ext/sqlite/sqlite.c' source file. Specifically, the 'rres' resource is not properly initialized before use which may trigger a double-free condition when an empty query is passed to the 'real_result_dtor()' function.
