Red Hat Bugzilla – Bug 107538
CAN-2003-0795 Zebra remote DoS
Last modified: 2014-08-31 19:25:28 EDT
Jonny Robertson reported a remote DoS condition exists in zebra when layer 3
access is possible to the telnet management port (2601/tcp).
By sending a telnet option delimiter with no actual option data, zebra will make
a bad memory call and SIGSEV.
I've assigned CAN-2003-0795 to track this issue.
Will be RHSA-2003:305.
Note also affects 2.1AW (not 2.1ES or 2.1WS which did not ship with zebra)
