|Gentoo Linux Security Advisory
Title: Openswan: Insecure temporary file creation (GLSA 200903-18)
Date: March 09, 2009
An insecure temporary file usage has been reported in Openswan, allowing for symlink attacks.
Openswan is an implementation of IPsec for Linux.
Vulnerable: < 2.4.13-r2
Unaffected: >= 2.4.13-r2
Architectures: All supported architectures
Dmitry E. Oboukhov reported that the IPSEC livetest tool does not handle the ipseclive.conn and ipsec.olts.remote.log temporary files securely.
A local attacker could perform symlink attacks to execute arbitrary code and overwrite arbitrary files with the privileges of the user running the application.
There is no known workaround at this time.
All Openswan users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/openswan-2.4.13-r2"
