Debian Security Advisory
DLA-535-1 xerces-c -- LTS security update
- Date Reported:
- 29 Jun 2016
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 828990.
In Mitre's CVE dictionary: CVE-2016-4463.
- More information:
Brandon Perry discovered that xerces-c, a validating XML parser library for C++, fails to successfully parse a DTD that is deeply nested, causing a stack overflow. A remote unauthenticated attacker can take advantage of this flaw to cause a denial of service against applications using the xerces-c library.
Additionally this update includes an enhancement to enable applications to fully disable DTD processing through the use of an environment variable (XERCES_DISABLE_DTD).
For Debian 7
Wheezy, these problems have been fixed in version 3.1.1-3+deb7u4.
We recommend that you upgrade your xerces-c packages.
