Severity:	high
Title:	arpwatch: Root privilege escalation
Date:	07/27/2020
Bugs:	#602552
ID:	202007-25

Synopsis

A vulnerability was discovered in arpwatch which may allow local attackers to gain root privileges.

Background

The ethernet monitor program; for keeping track of ethernet/ip address pairings.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/arpwatch	< 2.1.15-r11	>= 2.1.15-r11	All supported architectures

Description

It was discovered that Gentoo’s arpwatch ebuild made excessive permission operations on its data directories, possibly changing ownership of unintended files. This only affects OpenRC systems, as the flaw was exploitable via the init script.

Impact

A local attacker could escalate privileges.

Workaround

There is no known workaround at this time.

Resolution

All arpwatch users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose
      ">=net-analyzer/arpwatch-2.1.15-r11"
