Description Jan Lieskovsky 2009-10-27 13:49:57 UTC
An invalid pointer dereference flaw was found in the Wireshark's Paltalk
dissector. A remote attacker could provide a specially-crafted Paltalk
packet capture file, which once opened by an unsuspecting user would
lead to denial of service (Wireshark crash).

Comment 1 Jan Lieskovsky 2009-10-27 13:52:20 UTC
This issue does NOT affect the versions of the wireshark package, as shipped
with Red Hat Enterprise Linux 3, 4, or 5.

This issue affects the versions of the wireshark package, as shipped
with Fedora releases of 10, 11, and as scheduled to appear in Fedora
release of 12.
