Description |
35 |
=========== |
36 |
|
37 |
It was discovered that Gentoo’s BURP ebuild does not properly set |
38 |
permissions or place the pid file in a safe directory. Additionally, |
39 |
the first set of patches did not completely address this. As such, a |
40 |
revision has been made available that addresses all concerns of the |
41 |
initial report. |

Impact |
44 |
====== |
45 |
|
46 |
A local attacker could escalate privileges. |
47 |
|
48 |
Workaround |
49 |
========== |
50 |
|
51 |
Users should ensure the proper permissions are set as discussed in the |
52 |
referenced bugs. |
53 |
|
54 |
Resolution |
55 |
========== |
56 |
|
57 |
All BURP users should upgrade to the latest version: |
58 |
|
59 |
# emerge --sync |
60 |
# emerge --ask --oneshot --verbose ">=app-backup/burp-2.1.32-r1" |
