The filter_frame function in libavfilter/vf_fps.c in FFmpeg before 2.1 does not properly ensure the availability of FIFO content, which allows remote attackers to cause a denial of service (double free) or possibly have unspecified other impact via crafted data.

Security readout for executives and security teams

CVE-2013-7021 is an old FFmpeg flaw in media frame filtering. A crafted media input could make affected FFmpeg versions before 2.1 crash through a double free, disrupting services that process untrusted files or streams. The sources also mention possible unspecified impact, but provide no confirmed details. Exposure is most likely where FFmpeg before 2.1 is embedded or invoked to process media from users, partners, queues, or remote feeds. Systems using maintained vendor packages are less likely exposed, but packaged FFmpeg versions should be verified. Treat this as a targeted maintenance and resilience issue, not an emergency unless exposed systems process untrusted media at scale. Prioritize internet-facing upload, transcoding, or media-conversion services first. Mitigation focus: Inventory FFmpeg versions in servers, containers, appliances, and bundled application dependencies.; Upgrade FFmpeg to version 2.1 or a vendor-supported fixed package.; Follow Gentoo GLSA-201603-06 where Gentoo packages are used..
