Detailsinfo

A vulnerability, which was classified as critical, has been found in GStreamer up to 1.10.1 (Multimedia Processing Software). Affected by this issue is the function flx_decode_delta_fli of the file gst/flx/gstflxdec.c. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in the flx_decode_delta_fli function in gst/flx/gstflxdec.c in the FLIC decoder in GStreamer before 1.10.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by providing a 'write count' that goes beyond the initialized buffer.

The bug was discovered 12/21/2016. The weakness was published 01/27/2017 by Chris Evans (Website). The advisory is shared for download at rhn.redhat.com. This vulnerability is handled as CVE-2016-9636 since 11/23/2016. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available.
