CVE-2008-3910
dns2tcp before 0.4.1 does not properly handle negative values in a certain length field in the input argument to the (1) dns_simple_decode or (2) dns_decode function, which allows remote attackers to overwrite a buffer and have unspecified other impact.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
