The remote host is affected by the vulnerability described in GLSA-200512-06 (Ethereal: Buffer overflow in OSPF protocol dissector)
iDEFENSE reported a possible overflow due to the lack of bounds checking in the dissect_ospf_v3_address_prefix() function, part of the OSPF protocol dissector.
Impact :
An attacker might be able to craft a malicious network flow that would crash Ethereal. It may be possible, though unlikely, to exploit this flaw to execute arbitrary code with the permissions of the user running Ethereal, which could be the root user.
Workaround :
There is no known workaround at this time.
