Buffer overflow in Wireshark

1) Buffer overflow

EUVDB-ID: #VU42781

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2013-4080

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The dissect_r3_upstreamcommand_queryconfig function in epan/dissectors/packet-assa_r3.c in the Assa Abloy R3 dissector in Wireshark 1.8.x before 1.8.8 does not properly handle a zero-length item, which allows remote attackers to cause a denial of service (infinite loop, and CPU and memory consumption) via a crafted packet.

Mitigation

Install update from vendor's website.
