Description Jan Lieskovsky 2011-07-19 12:31:35 UTC 
An infinite loop was found in the way ANSI A Interface (IS-634/IOS) dissector of the Wireshark network traffic analyzer processed certain ANSI A MAP capture files. If Wireshark read a malformed packet off a network or opened a malicious packet capture file, it could lead to denial of service (Wireshark hang).

Jan, looks like Fedora wireshark updates due CVE-2011-2597 (bug #719782) were not scheduled yet. So I am going to use that bug and merge this issue with CVE-2011-2597, so both could be addressed at the same time.
