Synopsis

An insecure temporary file usage has been reported in Openswan, allowing for symlink attacks.

Background

Openswan is an implementation of IPsec for Linux.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-misc/openswan	< 2.4.13-r2	>= 2.4.13-r2	All supported architectures

Description

Dmitry E. Oboukhov reported that the IPSEC livetest tool does not handle the ipseclive.conn and ipsec.olts.remote.log temporary files securely.

Impact

Workaround

There is no known workaround at this time.

Resolution
