Technical Details:
A regression was found in the fix for PHP's XSLT transformations (CVE-2012-0057). Updated Linux Distribution Packages are now available to address this regression. For reference, the original advisory text follows. Several vulnerabilities have been discovered in PHP, the web scripting language. The Common Vulnerabilities and Exposures project identifies the following issues: CVE-2011-1938 The UNIX socket handling allowed attackers to trigger a buffer overflow via a long path name. CVE-2011-2483 The crypt_blowfish function did not properly handle 8-bit characters, which made it easier for attackers to determine a cleartext password by using knowledge of a password hash. CVE-2011-4566 When used on 32 bit platforms, the exif extension could be used to trigger an integer overflow in the exif_process_IFD_TAG function when processing a JPEG file. CVE-2011-4885 It was possible to trigger hash collisions predictably when parsing form parameters, which allows remote attackers to cause a denial of service by sending many crafted parameters. CVE-2012-0057 When applying a crafted XSLT transform, an attacker could write files to arbitrary places in the filesystem. NOTE: the fix for CVE-2011-2483 required changing the behaviour of this function: it is now incompatible with some old (wrongly) generated hashes for passwords containing 8-bit characters. See the Linux Distribution Package NEWS entry for details. This change has not been applied to the Lenny version of PHP. NOTE: at the time of release Linux Distribution Packages for some architectures are still being built. They will be installed into the archive as soon as they arrive. For the oldstable distribution (lenny), these problems have been fixed in version 5.2.6.dfsg.1-1+lenny15. For the stable distribution (squeeze), these problems have been fixed in version 5.3.3-7+squeeze6. For the testing distribution (wheezy) and unstable distribution (sid), these problems have been fixed in version 5.3.9-1.

We recommend that you upgrade your php5 Linux Distribution Packages.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
