Debian DSA-2399-2 : php5 - several vulnerabilities

high Nessus Plugin ID 57753


The remote Debian host is missing a security-related update.


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.


Upgrade the php5 packages.

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.
