Debian DLA-1674-1 : php5 security update

high Nessus Plugin ID 122101

Language:

Synopsis

The remote Debian host is missing a security update.

Description

php-pear in php5 contains CWE-502 (Deserialization of Untrusted Data) and CWE-915 (Improperly Controlled Modification of Dynamically-Determined Object Attributes) vulnerabilities in its Archive_Tar class. When extract is called without a specific prefix path, can trigger unserialization by crafting a tar file with `phar://[path_to_malicious_phar_file]` as path. Object injection can be used to trigger destruct in the loaded PHP classes, all with possible remote code execution that can result in files being deleted or possibly modified.

For Debian 8 'Jessie', this problem has been fixed in version 5.6.39+dfsg-0+deb8u2.

We recommend that you upgrade your php5 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
