Security Bulletin

This security bulletin contains one medium risk vulnerability.

1) Integer overflow

EUVDB-ID: #VU33560

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2017-5597

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

In Wireshark 2.2.0 to 2.2.3 and 2.0.0 to 2.0.9, the DHCPv6 dissector could go into a large loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-dhcpv6.c by changing a data type to avoid an integer overflow.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Wireshark: 2.0.0 - 2.2.3
