CVE-2008-4109 (GCVE-0-2008-4109)

Vulnerability from cvelistv5 – Published: 2008-09-17 18:06 – Updated: 2024-08-07 10:00

Summary

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.

Severity ?
