Comment: This advisory references vulnerabilities in products which run on 
         platforms other than Debian. It is recommended that administrators 
         running php5 check for an updated version of the software for their
         operating system.
         
         Stefan Esser discovered this vulnerability, and has advised that it 
         is greatly mitigated by the use of Suhosin-Extension, even in the

Debian Security Advisory DSA-2403-1                   security@debian.org

Package        : php5
Vulnerability  : code injection
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2012-0830 

Stefan Esser discovered that the implementation of the max_input_vars
configuration variable in a recent PHP security update was flawed such
that it allows remote attackers to crash PHP or potentially execute
code.

For the oldstable distribution (lenny), no fix is available at this time.

For the stable distribution (squeeze), this problem has been fixed in
version 5.3.3-7+squeeze7.

The testing distribution (wheezy) and unstable distribution (sid)
will be fixed soon.

We recommend that you upgrade your php5 packages.
