Background ========== Snort is a widely deployed intrusion detection program. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/snort < 2.6.1.3 >= 2.6.1.3 Description =========== The Snort DCE/RPC preprocessor does not properly reassemble certain types of fragmented SMB and DCE/RPC packets. Impact ====== A remote attacker could send specially crafted fragmented SMB or DCE/RPC packets, without the need to finish the TCP handshake, that would trigger a stack-based buffer overflow while being reassembled. This could lead to the execution of arbitrary code with the permissions of the user running the Snort preprocessor. Workaround ========== Disable the DCE/RPC processor by commenting 'preprocessor rpc_decode' and 'include $RULE_PATH/rpc.rules' from /etc/snort/snort.conf . Resolution ========== All Snort users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/snort-2.6.1.3" References ========== [ 1 ] CVE-2006-5276 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5276 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200703-01.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
