K14742 : OpenSSH vulnerability CVE-2008-4109

Security Advisory Description

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. (CVE-2008-4109)

Impact

This vulnerability in secure shell (SSH) may allow remote attackers to cause a denial-of-service (DoS) attack.
