PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

It was found that the hashing routine used by PHP arrays was susceptible to predictable hash collisions. If an HTTP POST request to a PHP application contained many parameters whose names map to the same hash value, a large amount of CPU time would be consumed. This flaw has been mitigated by adding a new configuration directive, max_input_vars, that limits the maximum number of parameters processed per request. By default, max_input_vars is set to 1000.
(CVE-2011-4885)

A use-after-free flaw was found in the PHP substr_replace() function.
If a PHP script used the same variable as multiple function arguments, a remote attacker could possibly use this to crash the PHP interpreter or, possibly, execute arbitrary code. (CVE-2011-1148)

An integer overflow flaw was found in the PHP exif extension. On 32-bit systems, a specially crafted image file could cause the PHP interpreter to crash or disclose portions of its memory when a PHP script tries to extract Exchangeable image file format (Exif) metadata from the image file. (CVE-2011-4566)

An insufficient input validation flaw, leading to a buffer over-read, was found in the PHP exif extension. A specially crafted image file could cause the PHP interpreter to crash when a PHP script tries to extract Exchangeable image file format (Exif) metadata from the image file. (CVE-2011-0708)

An integer overflow flaw was found in the PHP calendar extension. A remote attacker able to make a PHP script call SdnToJulian() with a large value could cause the PHP interpreter to crash. (CVE-2011-1466)

A bug in the PHP Streams component caused the PHP interpreter to crash if an FTP wrapper connection was made through an HTTP proxy. A remote attacker could possibly trigger this issue if a PHP script accepted an untrusted URL to connect to. (CVE-2011-1469)

An off-by-one flaw was found in PHP. If an attacker uploaded a file with a specially crafted file name it could cause a PHP script to attempt to write a file to the root (/) directory. By default, PHP runs as the 'apache' user, preventing it from writing to the root directory. (CVE-2011-2202)

All php users should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

A signedness issue was found in the way the PHP crypt() function handled 8-bit characters in passwords when using Blowfish hashing. Up to three characters immediately preceding a non-ASCII character (one with the high bit set) had no effect on the hash result, thus shortening the effective password length. This made brute-force guessing more efficient as several different passwords were hashed to the same value. (CVE-2011-2483)

Note: Due to the CVE-2011-2483 fix, after installing this update some users may not be able to log in to PHP applications that hash passwords with Blowfish using the PHP crypt() function. Refer to the upstream 'CRYPT_BLOWFISH security fix details' document, linked to in the References, for details.

An insufficient input validation flaw, leading to a buffer over-read, was found in the PHP exif extension. A specially crafted image file could cause the PHP interpreter to crash when a PHP script tries to extract Exchangeable image file format (Exif) metadata from the image file. (CVE-2011-0708)

An integer overflow flaw was found in the PHP calendar extension. A remote attacker able to make a PHP script call SdnToJulian() with a large value could cause the PHP interpreter to crash. (CVE-2011-1466)

Multiple memory leak flaws were found in the PHP OpenSSL extension. A remote attacker able to make a PHP script use openssl_encrypt() or openssl_decrypt() repeatedly could cause the PHP interpreter to use an excessive amount of memory. (CVE-2011-1468)

A use-after-free flaw was found in the PHP substr_replace() function.
If a PHP script used the same variable as multiple function arguments, a remote attacker could possibly use this to crash the PHP interpreter or, possibly, execute arbitrary code. (CVE-2011-1148)

A bug in the PHP Streams component caused the PHP interpreter to crash if an FTP wrapper connection was made through an HTTP proxy. A remote attacker could possibly trigger this issue if a PHP script accepted an untrusted URL to connect to. (CVE-2011-1469)

An integer signedness issue was found in the PHP zip extension. An attacker could use a specially crafted ZIP archive to cause the PHP interpreter to use an excessive amount of CPU time until the script execution time limit is reached. (CVE-2011-1471)

A stack-based buffer overflow flaw was found in the way the PHP socket extension handled long AF_UNIX socket addresses. An attacker able to make a PHP script connect to a long AF_UNIX socket address could use this flaw to crash the PHP interpreter. (CVE-2011-1938)

An off-by-one flaw was found in PHP. If an attacker uploaded a file with a specially crafted file name it could cause a PHP script to attempt to write a file to the root (/) directory. By default, PHP runs as the 'apache' user, preventing it from writing to the root directory. (CVE-2011-2202)

All php53 and php users should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.
