Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple heap-based buffer overflow vulnerabilities in libsndfile might |
| 19 |
allow remote attackers to execute arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
libsndfile is a C library for reading and writing files containing |
| 25 |
sampled sound. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 media-libs/libsndfile < 1.0.20 >= 1.0.20 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
The following vulnerabilities have been found in libsndfile: |
| 39 |
|
| 40 |
* Tobias Klein reported that the header_read() function in |
| 41 |
src/common.c uses user input for calculating a buffer size, possibly |
| 42 |
leading to a heap-based buffer overflow (CVE-2009-1788). |
| 43 |
|
| 44 |
* The vendor reported a boundary error in the aiff_read_header() |
| 45 |
function in src/aiff.c, possibly leading to a heap-based buffer |
| 46 |
overflow (CVE-2009-1791). |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A remote attacker could entice a user to open a specially crafted AIFF |
| 52 |
or VOC file in a program using libsndfile, possibly resulting in the |
| 53 |
execution of arbitrary code with the privileges of the user running the |
| 54 |
application. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. |
| 60 |
|
| 61 |
Resolution |
| 62 |
========== |
| 63 |
|
| 64 |
All libsndfile users should upgrade to the latest version: |
| 65 |
|
| 66 |
# emerge --sync |
| 67 |
# emerge --ask --oneshot --verbose ">=media-libs/libsndfile-1.0.20" |
| 68 |
|
