Description Martin Prpič 2015-03-13 14:15:48 UTC 
A flaw was found in tcpdump's ethernet printer. A remote attacker could use this flaw to cause tcpdump to crash, resulting in a denial of service.

Comment 1 Martin Prpič 2015-03-13 14:17:25 UTC 
Created tcpdump tracking bugs for this issue:

Affects: fedora-all [bug 1201799]
Comment 2 Stefan Cornelius 2015-03-18 18:31:26 UTC 
This is caused by missing sanity checks in the osi_print_cksum() function in print-isoclns.c.

The function may call the create_osi_cksum() function in checksum.c with invalid data. Fortunately, this seems to be exploitable for an application crash due to an out-of-bounds read only.
