Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
fbida is vulnerable to linking attacks, potentially allowing a local |
| 19 |
user to overwrite arbitrary files. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
fbida is a collection of image viewers and editors for the framebuffer |
| 25 |
console and X11. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 media-gfx/fbida < 2.03-r3 >= 2.03-r3 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Jan Braun has discovered that the "fbgs" script provided by fbida |
| 39 |
insecurely creates temporary files in the "/var/tmp" directory. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A local attacker could create links in the temporary file directory, |
| 45 |
pointing to a valid file somewhere on the filesystem. When an affected |
| 46 |
script is called, this could result in the file being overwritten with |
| 47 |
the rights of the user running the script. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All fbida users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=media-gfx/fbida-2.03-r3" |
| 61 |
|
