Description Vincent Danen 2011-11-01 17:01:56 EDT

An uninitialized variable in the CSN.1 dissector in Wireshark 1.6.0 through 1.6.2 could cause Wireshark to crash by reading a malformed packet trace file or if someone were to inject a malformed packet onto the the wire.  This is corrected in wireshark 1.6.3.

Comment 4 Huzaifa S. Sidhpurwala 2011-11-03 02:30:41 EDT

Statement:

Not vulnerable. This issue did not affect the versions of wireshark as shipped
with Red Hat Enterprise Linux 4, 5 and 6, as they did not include support for the CSN.1 dissector.
