A vulnerability was discovered in arpwatch which may allow local attackers to gain root privileges.
|Package||net-analyzer/arpwatch on all architectures|
|Affected versions||< 2.1.15-r11|
|Unaffected versions||>= 2.1.15-r11|
The ethernet monitor program; for keeping track of ethernet/ip address pairings.
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.
A local attacker could escalate privileges.
There is no known workaround at this time.
All arpwatch users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/arpwatch-2.1.15-r11"
