-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2399-1 security@xxxxxxxxxx http://www.debian.org/security/ Thijs Kinkhorst January 31, 2012 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : php5 Vulnerability : several Problem type : remote Debian-specific: no CVE ID : CVE-2011-1938 CVE-2011-2483 CVE-2011-4566 CVE-2011-4885 CVE-2012-0057 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 package NEWS entry for details. This change has not been applied to the Lenny version of PHP. For the oldstable distribution (lenny), these problems have been fixed in version 5.2.6.dfsg.1-1+lenny14. For the stable distribution (squeeze), these problems have been fixed in version 5.3.3-7+squeeze5. 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 packages.
