Summary
Vulnerability in GPAC MP4Box v2.4: segmentation violation in gf_hevc_read_sps_bs_internal function (media_tools/av_parsers.c). An attacker can cause a Denial of Service (DoS) by supplying crafted HEVC SPS data.
Risk Assessment
Risk of service disruption (DoS) by sending malicious HEVC SPS data to applications using GPAC MP4Box.
Recommendation
Update GPAC to the latest patched version. Restrict processing of untrusted HEVC streams.
