Debian DSA-2403-2 : php5 - code injection

High Nessus Plugin ID 57814

Synopsis

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

Description

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.

Solution

Upgrade the php5 packages.

For the oldstable distribution (lenny), this problem has been fixed in version 5.2.6.dfsg.1-1+lenny16.

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