Openswan IPsec Livetest Insecure Temporary File Creation Vulnerability
Openswan creates temporary files in an insecure manner.
An attacker with local access could potentially exploit these issues to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.
Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible.
UPDATE (March 9, 2009): The vendor disputes the validity of this issue, stating that the vulnerable code was incomplete and never run from within the application. The vendor also reports that the latest version of Openswan has disabled the offending code.
