Update ======
While working on the tcpdump issues solved in the original version of this GLSA, Simon L. 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"
