An exploitable denial-of-service vulnerability exists in the TXT record-parsing functionality of Videolabs libmicrodns 0.1.0.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.50%). 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 TXT record-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing the RDATA section in a TXT record in mDNS messages, multiple integer overflows can be triggered, leading to a denial of service. An attacker can send an mDNS message to trigger this vulnerability.
