CVE-2026-82820
A vulnerability was found in FLVMeta up to 1.2.2.
Does this matter?
Lower severity and a low EPSS score (0.36%). Track it; it rarely justifies an emergency change on its own.
Description
A vulnerability was found in FLVMeta up to 1.2.2. Affected is the function amf_string_new of the file src/amf.c of the component AMF String Processing. The manipulation of the argument length results in heap-based buffer overflow. The attack can be launched remotely. The exploit has been made public and could be used. The patch is identified as f412a33b9a84c2d1a9dee145a868feddbf64879e. A patch should be applied to remediate this issue. The project maintainer doubts the security impact: "While I acknowledged the bugs and provided fixes, I have yet to see any way to exploit these alleged vulnerabilities."
