35 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"
