Debian DSA-2742-1 : php5 - interpretation conflict

medium Nessus Plugin ID 69473

Language:

Synopsis

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

Description

It was discovered that PHP, a general-purpose scripting language commonly used for web application development, did not properly process embedded NUL characters in the subjectAltName extension of X.509 certificates. Depending on the application and with insufficient CA-level checks, this could be abused for impersonating other users.

Solution

Upgrade the php5 packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 5.3.3-7+squeeze17.

For the stable distribution (wheezy), this problem has been fixed in version 5.4.4-14+deb7u4.
