|Gentoo Linux Security Advisory
Title: Openswan: Denial of Service (GLSA 201203-13)
Exploitable: local, remote
Date: March 16, 2012
Bug(s): #372961, #389097
Multiple vulnerabilities in Openswan may create a Denial of Service
Openswan is an implementation of IPsec for Linux.
Vulnerable: < 2.6.37
Unaffected: >= 2.6.37
Architectures: All supported architectures
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:
NOTE: This is a legacy GLSA. Updates for all affected architectures are
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/openswan-2.6.37"
available since November 10, 2011. It is likely that your system is
already no longer affected by this issue.
