Gpac: Index-out-of-bounds in gf_vvc_parse_nalu_bs
OSS-Fuzz report: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=70392 ``` Crash type: Index-out-of-bounds Crash state: gf_vvc_parse_nalu_bs gf_inspect_dump_nalu_internal inspect_process ```
AI Analysis
Technical Summary
The vulnerability is an index-out-of-bounds error triggered in the gpac multimedia framework's function gf_vvc_parse_nalu_bs, which parses VVC (Versatile Video Coding) NAL units. This leads to a crash state identified by OSS-Fuzz, specifically during the inspection and dumping of NAL units. The affected versions include gpac 26.02.0 and versions from commit 99a7952e91938f8c0d16f2235b912de1fed6c1f8 onward. No CVSS score or detailed impact analysis is provided, and no patch or remediation guidance is currently documented.
Potential Impact
The vulnerability causes an application crash due to an index-out-of-bounds error during video data parsing. This may lead to denial of service or application instability when processing crafted VVC streams. There is no evidence of code execution or data corruption beyond the crash. No known exploitation in the wild has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory or OSS-Fuzz issue tracker for current remediation guidance. Until a fix is available, avoid processing untrusted VVC video streams with affected versions of gpac to mitigate risk.
