Synopsis ========
Multiple vulnerabilities in Openswan may create a Denial of Service condition.
Background ==========
Openswan is an implementation of IPsec for Linux.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/openswan < 2.6.37 >= 2.6.37
Description ===========
Two vulnerabilities have been found in Openswan:
* Improper permissions are used on /var/run/starter.pid and /var/lock/subsys/ipsec (CVE-2011-2147). * Openswan contains a use-after-free error in the cryptographic helper handler (CVE-2011-4073).
Impact ======
A remote authenticated attacker or a local attacker may be able to cause a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Openswan users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/openswan-2.6.37"
