CVE-2014-7937
HighSummary
Multiple off-by-one errors in libavcodec/vorbisdec.c in FFmpeg before 2.4.2 allow remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted Vorbis I data.
Risk Assessment
Organizations may be exposed to remote attacks that could lead to denial of service or other unforeseen consequences. Exploitation of this vulnerability could affect the availability of services using FFmpeg.
Recommendation
It is recommended to update FFmpeg to version 2.4.2 or later to mitigate these issues. Additionally, monitoring and analyzing network traffic may help in detecting attempts to exploit this vulnerability.
