 Mandriva Linux Security Advisory                         MDVSA-2013:231
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : openswan
 Date    : September 12, 2013
 Affected: Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been discovered and corrected in openswan:
 
 The IPSEC livetest tool in Openswan 2.4.12 and earlier, and
 2.6.x through 2.6.16, allows local users to overwrite arbitrary
 files and execute arbitrary code via a symlink attack on the (1)
 ipseclive.conn and (2) ipsec.olts.remote.log temporary files. NOTE:
 in many distributions and the upstream version, this tool has been
 disabled (CVE-2008-4190).
 
 The pluto IKE daemon in Openswan and Strongswan IPsec 2.6 before 2.6.21
 and 2.4 before 2.4.14, and Strongswan 4.2 before 4.2.14 and 2.8 before
 2.8.9, allows remote attackers to cause a denial of service (daemon
 crash and restart) via a crafted (1) R_U_THERE or (2) R_U_THERE_ACK
 Dead Peer Detection (DPD) IPsec IKE Notification message that triggers
 a NULL pointer dereference related to inconsistent ISAKMP state and
 the lack of a phase2 state association in DPD (CVE-2009-0790).
 
 The ASN.1 parser (pluto/asn1.c, libstrongswan/asn1/asn1.c,
 libstrongswan/asn1/asn1_parser.c) in (a) strongSwan 2.8 before 2.8.10,
 4.2 before 4.2.16, and 4.3 before 4.3.2; and (b) openSwan 2.6 before
 2.6.22 and 2.4 before 2.4.15 allows remote attackers to cause a denial
 of service (pluto IKE daemon crash) via an X.509 certificate with (1)
 crafted Relative Distinguished Names (RDNs), (2) a crafted UTCTIME
 string, or (3) a crafted GENERALIZEDTIME string (CVE-2009-2185).
 
 Use-after-free vulnerability in the cryptographic helper handler
 functionality in Openswan 2.3.0 through 2.6.36 allows remote
 authenticated users to cause a denial of service (pluto IKE daemon
 crash) via vectors related to the (1) quick_outI1_continue and (2)
 quick_outI1 functions (CVE-2011-4073).
 
 Buffer overflow in the atodn function in Openswan before 2.6.39,
 when Opportunistic Encryption is enabled and an RSA key is being
 used, allows remote attackers to cause a denial of service (pluto IKE
 daemon crash) and possibly execute arbitrary code via crafted DNS TXT
 records. NOTE: this might be the same vulnerability as CVE-2013-2052
 and CVE-2013-2054 (CVE-2013-2053).
 
 The updated packages have been patched to correct these issues.
