SUSE SLED12 / SLES12 Security Update : DirectFB (SUSE-SU-2015:0839-1)

critical Nessus Plugin ID 83724
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.

Synopsis

The remote SUSE host is missing one or more security updates.

Description

DirectFB was updated to fix two security issues.

The following vulnerabilities were fixed :

- CVE-2014-2977: Multiple integer signedness errors could allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers a stack-based buffer overflow.

- CVE-2014-2978: Remote attackers could cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers an out-of-bounds write.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
