Description

This security bulletin contains information about 1 security vulnerability.


1) Resource management error (CVE-ID: CVE-2015-5312)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.3 does not properly prevent entity expansion, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data, a different vulnerability than CVE-2014-3660.
