Debian Security Advisory

DSA-2492-1 php5 -- buffer overflow

Date Reported:

10 Jun 2012

Affected Packages:

php5

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2012-2386.

More information:

The Phar extension for PHP does not properly handle crafted tar files, leading to a heap-based buffer overflow. PHP applications processing tar files could crash or, potentially, execute arbitrary code.

In addition, this update addresses a regression which caused a crash when accessing a global object that is returned as $this from __get.

For the stable distribution (squeeze), this problem has been fixed in version 5.3.3-7+squeeze13.

For the testing distribution (wheezy) and the unstable distribution (sid), this problem has been fixed in version 5.4.4~rc1-1.

We recommend that you upgrade your php5 packages.
