Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2011-3483)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

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."


2) Input validation error (CVE-ID: CVE-2011-3484)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

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.


3) Resource management error (CVE-ID: CVE-2011-3482)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

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.


4) Resource management error (CVE-ID: CVE-2011-3266)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The proto_tree_add_item function in Wireshark 1.6.0 through 1.6.1 and 1.4.0 through 1.4.8, when the IKEv1 protocol dissector is used, allows user-assisted remote attackers to cause a denial of service (infinite loop) via vectors involving a malformed IKE packet and many items in a tree.
