Security Bulletin

This security bulletin contains one medium risk vulnerability.

1) Buffer overflow

EUVDB-ID: #VU33465

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-2019-10899

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the SRVLOC dissector could crash. This was addressed in epan/dissectors/packet-srvloc.c by preventing a heap-based buffer under-read.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Wireshark: 3.0.0

Fedora: 3.0.0 - 30
