Synopsis

A vulnerability has been discovered in uptimed which could result in
root privilege escalation.

Background

uptimed is a system uptime record daemon that keeps track of your
highest uptimes.

Affected packages

-------------------------------------------------------------------  
 Package              /     Vulnerable     /            Unaffected  
-------------------------------------------------------------------  

1 app-misc/uptimed < 0.4.6-r1 >= 0.4.6-r1

Description

Via unnecessary file ownership modifications in the pkg_postinst ebuild
phase, the uptimed user could change arbitrary files to be owned by the
uptimed user at emerge-time.

Impact

The uptimed user could achieve root privileges when the uptimed package
is emerged.

Workaround

There is no known workaround at this time.

Resolution

All uptimed users should upgrade to the latest version:

emerge --sync

emerge --ask --oneshot --verbose “>=app-misc/uptimed-0.4.6-r1”
