cups-filters -- buffer overflow in texttopdf size allocation

Stefan Cornelius from Red Hat reports:

A heap-based buffer overflow was discovered in the way the
texttopdf utility of cups-filters 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.

Till Kamppeter reports:

texttopdf: Fixed buffer overflow on size allocation of texttopdf
when working with extremely small line sizes, which causes the size
calculation to result in 0 (CVE-2015-3258, thanks to Stefan
Cornelius from Red Hat for the patch).
