Last modified
CVE-2018-4011 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. An exploitable integer underflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall, version 7003. When parsing SRV records in an mDNS packet, the "RDLENGTH" value is handled incorrectly, leading to an out-of-bounds access that crashes the mdnscap process. EPSS estimates a 1.32% chance of exploitation in the next 30 days.
