Package        : xml-security-c
Version        : 1.7.2-3+deb8u2


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.

these updates to your system and frequently asked questions can be
