Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Blam doesn't properly handle environment variables, potentially |
| 19 |
allowing a local attacker to execute arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Blam is an RSS and Atom feed reader for GNOME written in C#. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 net-news/blam < 1.8.4 >= 1.8.4 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
The "/usr/bin/blam" script sets the "LD_LIBRARY_PATH" environment |
| 38 |
variable incorrectly, which might result in the current working |
| 39 |
directory (.) being included when searching for dynamically linked |
| 40 |
libraries of the Mono Runtime application. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A local attacker could entice a user to run Blam in a directory |
| 46 |
containing a specially crafted library file which could result in the |
| 47 |
execution of arbitrary code with the privileges of the user running |
| 48 |
Blam. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
Do not run Blam from an untrusted working directory. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Blam users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=net-news/blam-1.8.4" |
| 62 |
|
