Synopsis |
19 |
======== |
20 |
|
21 |
Multiple integer overflow vulnerabilities were found in FLAC possibly |
22 |
allowing for the execution of arbitrary code. |
23 |
|
24 |
Background |
25 |
========== |
26 |
|
27 |
The Xiph.org Free Lossless Audio Codec (FLAC) library is the reference |
28 |
implementation of the FLAC audio file format. It contains encoders and |
29 |
decoders in library and executable form. |
30 |
|
31 |
Affected packages |
32 |
================= |
33 |
|

35 |
Package / Vulnerable / Unaffected |

Description |
40 |
=========== |
41 |
|
42 |
Sean de Regge reported multiple integer overflows when processing FLAC |
43 |
media files that could lead to improper memory allocations resulting in |
44 |
heap-based buffer overflows. |
45 |
|
46 |
Impact |
47 |
====== |
48 |
|
49 |
A remote attacker could entice a user to open a specially crafted FLAC |
50 |
file or network stream with an application using FLAC. This might lead |
51 |
to the execution of arbitrary code with privileges of the user playing |
52 |
the file. |
53 |
|
54 |
Workaround |
55 |
========== |
56 |
|
57 |
There is no known workaround at this time. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |
All FLAC users should upgrade to the latest version: |
63 |
|
64 |
# emerge --sync |
65 |
# emerge --ask --oneshot --verbose ">=media-libs/flac-1.2.1-r1" |
66 |
|
67 |
You should also run revdep-rebuild to rebuild any packages that depend |
68 |
on older versions of FLAC: |
69 |
|
70 |
# revdep-rebuild --library=libFLAC.* |
71 |
|
