It is recommended that administrators running xerces-c check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - - ------------------------------------------------------------------------- Debian Security Advisory DSA-3610-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso June 29, 2016 https://www.debian.org/security/faq - - ------------------------------------------------------------------------- Package : xerces-c CVE ID : CVE-2016-4463 Debian Bug : 828990 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 the stable distribution (jessie), this problem has been fixed in version 3.1.1-5.1+deb8u3. We recommend that you upgrade your xerces-c packages.
