CVE-2020-6078 log

Source
Severity Medium
Remote Yes
Type Denial of service
Description
An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages in mdns_recv, the return value of the mdns_read_header function is not checked, leading to an uninitialized variable usage that eventually results in a null pointer dereference, leading to service crash. An attacker can send a series of mDNS messages to trigger this vulnerability.
