Severity: normal
Exploitable: local
Date: March 09, 2009
Bug(s): #238574
ID: 200903-18
Synopsis
An insecure temporary file usage has been reported in Openswan, allowing for symlink attacks.
Background

Vulnerable: < 2.4.13-r2
Unaffected: >= 2.4.13-r2

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
A local attacker could perform symlink attacks to execute arbitrary code and overwrite arbitrary files with the privileges of the user running the application.
Workaround
There is no known workaround at this time.

# emerge --ask --oneshot --verbose ">=net-misc/openswan-2.4.13-r2" |
