Red Hat Product Errata RHSA-2012:0509 0 normal SHIPPED_LIVE Moderate: wireshark security update 2012-04-23 20:47:35 UTC

Description Jan Lieskovsky 2011-06-02 12:51:41 UTC 
A double free flaw was found in the way Wireshark uncompressed a zlib
compressed packet inside a message of tvbuff buffer. A remote attacker
could create a specially-crafted capture file, which once opened, by a
local, unsuspecting user could lead to wireshark application crash.
