Debian Security Advisory DSA-2922-1 security@debian.org
http://www.debian.org/security/ Yves-Alexis Perez
May 05, 2014 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : strongswan
CVE ID : CVE-2014-2891
A vulnerability has been found in the ASN.1 parser of strongSwan, an
IKE/IPsec suite used to establish IPsec protected links.
By sending a crafted ID_DER_ASN1_DN ID payload to a vulnerable pluto or
charon daemon, a malicious remote user can provoke a null pointer
dereference in the daemon parsing the identity, leading to a crash and a
denial of service.
For the oldstable distribution (squeeze), this problem has been fixed in
version 4.4.1-5.6.
For the stable distribution (wheezy), this problem has been fixed in
version 4.5.2-1.5+deb7u4.
For the testing distribution (jessie), this problem has been fixed in
version 5.1.2-1.
For the unstable distribution (sid), this problem has been fixed in
version 5.1.2-1.
We recommend that you upgrade your strongswan packages.
