CVE-2009-4633

Publication date 9 February 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

vorbis_dec.c in FFmpeg 0.5 uses an assignment operator when a comparison operator was intended, which might allow remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted file that modifies a loop counter and triggers a heap-based buffer overflow.
