CVE-2015-2318 not yet assigned priority: Debian including 1 source packages (mono), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
The TLS stack in Mono before 3.12.1 allows man-in-the-middle attackers to conduct message skipping attacks and consequently impersonate clients by leveraging missing handshake state validation, aka a "SMACK SKIP-TLS" issue.
