RHSA-2011:1423 - Moderate: php53 and php security update
Synopsis
Moderate: php53 and php security update
Type/Severity
Security Advisory Moderate
Topic
Updated php53 and php packages that fix several security issues are now available for Red Hat Enterprise Linux 5 and 6 respectively.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Description
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.
