Synopsis |
16 |
======== |
17 |

|
21 |
Background |
22 |
========== |
23 |
|
24 |
FFmpeg is a complete solution to record, convert and stream audio and |
25 |
video. gst-plugins-ffmpeg is a FFmpeg based gstreamer plugin which |
26 |
includes a vulnerable copy of FFmpeg code. Mplayer is a multimedia |
27 |
player which also includes a vulnerable copy of the code. |

49 |
(CVE-2008-3162). |
50 |
|
51 |
* Multiple buffer overflows in libavformat/utils.c (CVE-2008-4866). |
52 |
|
53 |

54 |
|
55 |
* An unspecified vulnerability in the avcodec_close() function in |
56 |
libavcodec/utils.c (CVE-2008-4868). |
57 |
|
58 |
* Unspecified memory leaks (CVE-2008-4869). |
59 |
|
60 |

Impact |
65 |
====== |
66 |
|
67 |
A remote attacker could entice a user to open a specially crafted media |
68 |
file, possibly leading to the execution of arbitrary code with the |
69 |
privileges of the user running the application, or a Denial of Service. |
70 |
|
71 |
Workaround |
72 |
========== |
73 |
|
74 |
There is no known workaround at this time. |
75 |
|
76 |
