The g2m_init_buffers function in libavcodec/g2meet.c in FFmpeg before 2.1 uses an incorrect ordering of arithmetic operations, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Go2Webinar data.

Security readout for executives and security teams

CVE-2013-7013 is a flaw in FFmpeg's Go2Webinar decoder. A maliciously crafted Go2Webinar data stream could crash software using vulnerable FFmpeg versions, causing service disruption. The sources also mention possible unspecified impact, but provide no confirmed detail beyond out-of-bounds array access and denial of service. Exposure is most likely where servers, desktop tools, or embedded products process untrusted media through FFmpeg/libavcodec versions before 2.1, especially Go2Webinar or G2M content. Modern vendor packages are likely fixed, but bundled or statically linked FFmpeg copies need separate review. Treat this as a legacy media-processing risk. Prioritize remediation if untrusted media is accepted from users, partners, or the internet. For systems already on supported FFmpeg packages, confirm status and record closure rather than escalating as an emergency. Mitigation focus: Upgrade FFmpeg/libavcodec to 2.1 or a vendor-supported fixed package.; Patch applications that bundle or statically link vulnerable FFmpeg code.; Restrict processing of untrusted Go2Webinar or G2M media until fixed..
