CVE-2020-6077
An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
