GLSA 201203-13: Openswan: Denial of Service
|Title:||Openswan: Denial of Service|
SynopsisMultiple vulnerabilities in Openswan may create a Denial of Service condition.
Openswan is an implementation of IPsec for Linux.
|net-misc/openswan||< 2.6.37||>= 2.6.37||All supported architectures|
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).
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:
# 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.
