| ID: | 202107-11 |
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 | Architecture(s) |
|---|---|---|---|
| app-admin/doas | < 6.8.1 | >= 6.8.1 | All supported architectures |
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"
