Multiple vulnerabilities have been found in faad2, the Freeware Advanced Audio Coder :
CVE-2018-20194 CVE-2018-20197
Improper handling of implicit channel mapping reconfiguration leads to multiple heap based buffer overflow issues. These flaws might be leveraged by remote attackers to cause DoS.
CVE-2018-20198 CVE-2018-20362
Insufficient user input validation in the sbr_hfadj module leads to stack-based buffer underflow issues. These flaws might be leveraged by remote attackers to cause DoS or any other unspecified impact.
For Debian 8 ‘Jessie’, these problems have been fixed in version 2.7-8+deb8u2.
We recommend that you upgrade your faad2 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.
