Synopsis: Important: openswan security update Advisory ID: SLSA-2013:0827-1 Issue Date: 2013-05-15 CVE Numbers: CVE-2013-2053 -- A buffer overflow flaw was found in Openswan. If Opportunistic Encryption were enabled ("oe=yes" in "/etc/ipsec.conf") and an RSA key configured, an attacker able to cause a system to perform a DNS lookup for an attacker- controlled domain containing malicious records (such as by sending an email that triggers a DKIM or SPF DNS record lookup) could cause Openswan's pluto IKE daemon to crash or, potentially, execute arbitrary code with root privileges. With "oe=yes" but no RSA key configured, the issue can only be triggered by attackers on the local network who can control the reverse DNS entry of the target system. Opportunistic Encryption is disabled by default. (CVE-2013-2053) After installing this update, the ipsec service will be restarted automatically. -- SL5 x86_64 openswan-2.6.32-5.el5_9.x86_64.rpm openswan-debuginfo-2.6.32-5.el5_9.x86_64.rpm openswan-doc-2.6.32-5.el5_9.x86_64.rpm i386 openswan-2.6.32-5.el5_9.i386.rpm openswan-debuginfo-2.6.32-5.el5_9.i386.rpm openswan-doc-2.6.32-5.el5_9.i386.rpm SL6 x86_64 openswan-2.6.32-20.el6_4.x86_64.rpm openswan-debuginfo-2.6.32-20.el6_4.x86_64.rpm openswan-doc-2.6.32-20.el6_4.x86_64.rpm i386 openswan-2.6.32-20.el6_4.i686.rpm openswan-debuginfo-2.6.32-20.el6_4.i686.rpm openswan-doc-2.6.32-20.el6_4.i686.rpm - Scientific Linux Development Team
