1) Input validation error

EUVDB-ID: #VU33906

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-2478

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

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.

Vulnerable software versions
