Description

The remote host is affected by the vulnerability described in GLSA-200903-33 (FFmpeg: Multiple vulnerabilities)

Multiple vulnerabilities were found in FFmpeg:
astrange     reported a stack-based buffer overflow in the str_read_packet() in     libavformat/psxstr.c when processing .str files (CVE-2008-3162).
Multiple buffer overflows in libavformat/utils.c     (CVE-2008-4866).
A buffer overflow in libavcodec/dca.c     (CVE-2008-4867).
An unspecified vulnerability in the     avcodec_close() function in libavcodec/utils.c (CVE-2008-4868).
Unspecified memory leaks (CVE-2008-4869).
Tobias Klein     repoerted a NULL pointer dereference due to an integer signedness error     in the fourxm_read_header() function in libavformat/4xm.c     (CVE-2009-0385).

Impact :

A remote attacker could entice a user to open a specially crafted media     file, possibly leading to the execution of arbitrary code with the     privileges of the user running the application, or a Denial of Service.

Workaround :

There is no known workaround at this time.
