CVE-2020-6077 is fixed in libmicrodns0 on 1 platform by libmicrodns0 0.0.8-1ubuntu0.1~esm1 (version 0.0.8-1ubuntu0.1~esm1), released March 24, 2020. It is not reported as exploited. Patch Radar priority: Routine.
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.
