Several vulnerabilities were discovered in libcaca, a graphics library that outputs text: integer overflows, floating point exceptions or invalid memory reads may lead to a denial of service (application crash) if a malformed image file is processed.
For Debian 8 ‘Jessie’, these problems have been fixed in version 0.99.beta19-2+deb8u1.
We recommend that you upgrade your libcaca 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.
