Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A buffer overflow vulnerability has been discovered in libsndfile. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
libsndfile is a library for reading and writing various formats of |
| 24 |
audio files including WAV and FLAC. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 media-libs/libsndfile < 1.0.17-r1 >= 1.0.17-r1 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Robert Buchholz of the Gentoo Security team discovered that the |
| 38 |
flac_buffer_copy() function does not correctly handle FLAC streams with |
| 39 |
variable block sizes which leads to a heap-based buffer overflow |
| 40 |
(CVE-2007-4974). |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A remote attacker could exploit this vulnerability by enticing a user |
| 46 |
to open a specially crafted FLAC file or network stream with an |
| 47 |
application using libsndfile. This might lead to the execution of |
| 48 |
arbitrary code with privileges of the user playing the file. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All libsndfile users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=media-libs/libsndfile-1.0.17-r1" |
| 62 |
|
