CVE-2013-0238 high priority: Debian including 1 source packages (ircd-hybrid), 4 status rows across 4 suites (bookworm, bullseye, sid, trixie): resolved 4.
The try_parse_v4_netmask function in hostmask.c in IRCD-Hybrid before 8.0.6 does not properly validate masks, which allows remote attackers to cause a denial of service (crash) via a mask that causes a negative number to be parsed.
