Description |
36 |
=========== |
37 |
|
38 |
It was discovered that Gentoo’s arpwatch ebuild made excessive |
39 |
permission operations on its data directories, possibly changing |
40 |
ownership of unintended files. This only affects OpenRC systems, as the |
41 |
flaw was exploitable via the init script. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
A local attacker could escalate privileges. |
47 |
|
48 |
Workaround |
49 |
========== |
50 |
|
51 |
There is no known workaround at this time. |
52 |
|
53 |
Resolution |
54 |
========== |
55 |
|
56 |
All arpwatch users should upgrade to the latest version: |
57 |
|
58 |
# emerge --sync |
59 |
# emerge --ask --oneshot -v ">=net-analyzer/arpwatch-2.1.15-r11" |
