Synopsis ========
A vulnerability in OpenDoas could lead to privilege escalation.
Background ==========
OpenDoas allows users to run commands as other users.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/doas < 6.8.1 >= 6.8.1
Description ===========
OpenDoas does not properly filter the PATH variable from the resulting shell after escalating privileges.
Impact ======
A local attacker with control of a user's PATH variable could escalate privileges if that user uses OpenDoas with a poisoned PATH variable.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All OpenDoas users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/doas-6.8.1"
