Synopsis

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

Description

Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development. The Common Vulnerabilities and Exposures project identifies the following issues :

- CVE-2013-6420 Stefan Esser reported possible memory corruption in openssl_x509_parse().

- CVE-2013-6712 Creating DateInterval objects from parsed ISO dates was not properly restricted, which allowed to cause a denial of service.

In addition, the update for Debian 7 'Wheezy' contains several bugfixes originally targeted for the upcoming Wheezy point release.

Solution

Upgrade the php5 packages.

For the oldstable distribution (squeeze), these problems have been fixed in version 5.3.3-7+squeeze18.

For the stable distribution (wheezy), these problems have been fixed in version 5.4.4-14+deb7u7.
