AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Crafted SEI data in FFmpeg before 0.10 causes infinite loop in h264 decoder, leading to denial of service.

Vulnerability

The vulnerability is in the ff_h264_decode_sei function in libavcodec/h264_sei.c of FFmpeg. Crafted Supplemental Enhancement Information (SEI) data triggers an infinite loop. Affected versions are FFmpeg before 0.10.

Exploitation

An attacker can exploit this by providing a specially crafted multimedia file containing malicious SEI data. No authentication is required; the attacker only needs to deliver the file to a user or service using FFmpeg to decode it.

Impact

Successful exploitation causes an infinite loop, leading to a denial of service (DoS) condition.

Mitigation

The vulnerability is fixed in FFmpeg version 0.10 and later. Users should upgrade to at least version 0.10. No workarounds are documented in the available references.
