Openswan is an implementation of IPsec for Linux.
Multiple vulnerabilities have been discovered in Openswan:
<li>Gerd v. Egidy reported a NULL pointer dereference in the Dead Peer
Detection of the pluto IKE daemon as included in Openswan
<li>The Orange Labs vulnerability research team
discovered multiple vulnerabilities in the ASN.1 parser
<impact type="normal">
A remote attacker could exploit these vulnerabilities by sending
specially crafted R_U_THERE or R_U_THERE_ACK packets, or a specially
crafted X.509 certificate containing a malicious Relative Distinguished
Name (RDN), UTCTIME string or GENERALIZEDTIME string to cause a Denial
of Service of the pluto IKE daemon.
There is no known workaround at this time.
All Openswan users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/openswan-2.4.15&quot;</code>
