Debian DLA-1631-1 : libcaca security update

high Nessus Plugin ID 121055
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security update.


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.


Upgrade the affected caca-utils, libcaca-dev, and libcaca0 packages.
