Description Stefan Cornelius 2015-07-03 08:28:41 UTC

An integer overflow flaw leading to a heap-based buffer overflow was
discovered in the way the texttopdf utility of cups-filter processed
print jobs with a specially crafted line size. An attacker being able
to submit print jobs could exploit this flaw to crash texttopdf or,
possibly, execute arbitrary code with the privileges of the 'lp' user.

Comment in
http://bzr.linuxfoundation.org/loggerhead/openprinting/cups-filters/revision/7365
claims it's CVE-2015-3259 (not 3279).

Comment 2 Tim Waugh 2015-07-03 14:05:47 UTC

That was my mistake. The correct name is CVE-2015-3279.
