CVSS v2.0

6.8

Medium

Base vector

AV:N/AC:M/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions FFmpeg versions prior to 2.1

Description The issue is related to the get siz function in libavcodec/jpeg2000dec.c, which does not prevent attempts to use non-zero image offsets. This allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.

Recommendations For versions prior to 2.1, update to version 2.1 or later to resolve the issue. As a temporary workaround, consider restricting the use of the get siz function in libavcodec/jpeg2000dec.c until a patch is available.
