Mandriva Linux Security Advisory MDVSA-2011:138
http://www.mandriva.com/security/

Package : wireshark
Date : September 28, 2011
Affected: 2011.
_______________________________________________________________________
Problem Description:
This advisory updates wireshark to the latest version (1.6.2), fixing
several security issues:
Untrusted search path vulnerability in Wireshark 1.4.x before 1.4.9
and 1.6.x before 1.6.2 allows local users to gain privileges via a
Trojan horse Lua script in an unspecified directory (CVE-2011-3360).
The csnStreamDissector function in epan/dissectors/packet-csn1.c in the
CSN.1 dissector in Wireshark 1.6.x before 1.6.2 does not initialize
a certain structure member, which allows remote attackers to cause
a denial of service (application crash) via a malformed packet
(CVE-2011-3482).
Wireshark 1.6.x before 1.6.2 allows remote attackers to cause a
denial of service (application crash) via a malformed capture file
that leads to an invalid root tvbuff, related to a buffer exception
handling vulnerability. (CVE-2011-3483).
The unxorFrame function in epan/dissectors/packet-opensafety.c in the
OpenSafety dissector in Wireshark 1.6.x before 1.6.2 does not properly
validate a certain frame size, which allows remote attackers to cause
a denial of service (loop and application crash) via a malformed packet
(CVE-2011-3484).
The updated packages have been upgraded to the latest 1.6.x version
(1.6.2) which is not vulnerable to these issues.
