Description

A vulnerability in xml-security-c, a library for the XML Digital Security specification, has been found. Different KeyInfo combinations, like signatures without public key, result in incomplete DSA structures that crash openssl during verification.

This vulnerability does not have a CVE identifier yet.

For Debian 8 'Jessie', this problem has been fixed in version 1.7.2-3+deb8u2.

We recommend that you upgrade your xml-security-c 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.
