DLA-470-1 libksba -- LTS security update

Date Reported:
13 May 2016
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2016-4579.
More information:

It was discovered that there was a possible read access beyond a buffer vulnerability in libksba, a X.509 and CMS certificate support library.

The returned length of the object from _ksba_ber_parse_tl (ti.length) was not always checked against the actual buffer length, thus leading to a read access after the end of the buffer and thus a SEGV.

For Debian 7 Wheezy, this issue has been fixed in libksba version 1.2.0-2+deb7u2.

We recommend that you upgrade your libksba packages.
