EUVDB-ID: #VU32765

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/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-2012-4292

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_stun_message function in epan/dissectors/packet-stun.c in the STUN dissector in Wireshark 1.4.x before 1.4.15, 1.6.x before 1.6.10, and 1.8.x before 1.8.2 does not properly interact with key-destruction behavior in a certain tree library, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

Mitigation

Install update from vendor's website.
