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

|
21 |
Background |
22 |
========== |
23 |
|
24 |

26 |
Vorbis files. |

Description |
37 |
=========== |
38 |

Impact |
43 |
====== |
44 |
|
45 |
A remote attacker could entice a user to play a specially crafted OGG |
46 |
Vorbis file using an application that uses libvorbis, possibly |
47 |
resulting in the execution of arbitrary code with the privileges of the |
48 |
user running the application, or a Denial of Service. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All libvorbis users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose =media-libs/libvorbis-1.2.3 |
