Gentoo Linux Security Advisory
||GLSA 201203-13 / Openswan
||March 16, 2012
||March 16, 2012: 1
All supported architectures
Multiple vulnerabilities in Openswan may create a Denial of Service
Openswan is an implementation of IPsec for Linux.
Two vulnerabilities have been found in Openswan:
- Improper permissions are used on /var/run/starter.pid and
- Openswan contains a use-after-free error in the cryptographic helper
A remote authenticated attacker or a local attacker may be able to cause
a Denial of Service condition.
There is no known workaround at this time.
All Openswan users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/openswan-2.6.37"
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since November 10, 2011. It is likely that your system is
already no longer affected by this issue.
