Description

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

The dissect_server_info function in epan/dissectors/packet-ms-mms.c in the MS-MMS dissector in Wireshark 1.6.x before 1.6.14 and 1.8.x before 1.8.6 does not properly manage string lengths, which allows remote attackers to cause a denial of service (application crash) via a malformed packet that (1) triggers an integer overflow or (2) has embedded '' characters in a string.

Mitigation
Install update from vendor's website.
