CVE-2008-4109

no score yetEPSS 29%

openbsd openssh: no CVSS score yet. EPSS 29% chance of exploitation in the next 30 days.

A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051.

EPSS: 29% chance of exploitation in the next 30 days; higher than 98% of CVEs (scores of 2026-10-31)
