Nielsen from FreeBSD Security Team discovered a similar infinite loop DoS vulnerability in the BGP handling code (CAN-2005-1267). New packages have been released to address this new issue. The updated sections appear below. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/tcpdump < 3.8.3-r3 >= 3.8.3-r3 Description =========== TCPDump improperly handles and decodes ISIS (CAN-2005-1278), BGP (CAN-2005-1267, CAN-2005-1279), LDP (CAN-2005-1279) and RSVP (CAN-2005-1280) packets. TCPDump might loop endlessly after receiving malformed packets. Resolution ========== All TCPDump users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-3.8.3-r3" References ========== [ 1 ] CAN-2005-1267 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2005-1267 [ 2 ] CAN-2005-1278 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2005-1278 [ 3 ] CAN-2005-1279 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2005-1279 [ 4 ] CAN-2005-1280 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2005-1280 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-06.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.
