DLA-1674-1 php5 -- LTS security update

Date Reported:

12 Feb 2019

Affected Packages:

php5

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2018-1000888.

More information:

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.
