Package        : libcaca
Version        : 0.99.beta19-2+deb8u1
CVE ID         : CVE-2018-20544 CVE-2018-20546 CVE-2018-20547
                 CVE-2018-20549
Debian Bug     : 917807

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.
