Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A heap overflow in mpg123 was discovered, which could result in the |
| 19 |
execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
mpg123 is a real time audio player designed for the MPEG format. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 media-sound/mpg123 < 0.59s-r11 >= 0.59s-r11 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
In httpdget.c, a variable is assigned to the heap, and is supposed to |
| 38 |
receive a smaller allocation. As this variable was not terminated |
| 39 |
properly, strncpy() will overwrite the data assigned next in memory. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
By enticing a user to visit a malicious URL, an attacker could possibly |
| 45 |
execute arbitrary code with the rights of the user running mpg123. |
| 46 |
|
| 47 |
Workaround |
| 48 |
========== |
| 49 |
|
| 50 |
There is no known workaround at this time. |
| 51 |
|
| 52 |
Resolution |
| 53 |
========== |
| 54 |
|
| 55 |
All mpg123 users should update to the latest version: |
| 56 |
|
| 57 |
# emerge --sync |
| 58 |
# emerge --ask --oneshot --verbose ">=media-sound/mpg123-0.59s-r11" |
| 59 |
