Name of the Vulnerable Software and Affected Versions FFmpeg versions through 3.4.2

Description The issue is related to a buffer data reading beyond valid boundaries in the export function of the libavfilter/vf signature.c component of the FFmpeg multimedia library. This can be exploited by a remote attacker using a specially crafted long file, potentially allowing access to confidential data, disrupting data integrity, and causing a denial of service.

Recommendations For FFmpeg versions through 3.4.2, consider updating to a version that contains a fix for this issue, as using a long filename can cause a denial of service or potentially have other unspecified impacts. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
