CVE-2026-52297
Description
A flaw was found in FFmpeg. An out-of-bounds read can occur when a specially crafted MOV file is parsed due to insufficiently padded extradata. This vulnerability can lead to an application crash, resulting in a denial of service.
Statement
To exploit this issue, an attacker needs to convince a user to parse a specially crafted MOV file, limiting its exposure. Furthermore, this issue can cause an application crash with no other security impact. For these reasons, this vulnerability has been rated with a moderate severity.
Mitigation
Do not parse untrusted files with the MOV demuxer in FFmpeg.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
