CVE-2020-6077 (GCVE-0-2020-6077)

Vulnerability from cvelistv5 – Published: 2020-03-24 20:39 – Updated: 2024-08-04 08:47

Summary

An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages, the implementation does not properly keep track of the available data in the message, possibly leading to an out-of-bounds read that would result in a denial of service. An attacker can send an mDNS message to trigger this vulnerability.

Severity

7.5 (High)
