What is CVE-2006-5229?
CVE-2006-5229 is a low-severity vulnerability in OpenSSH, published on 10 Oct 2006. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime. NOTE: as of 20061014, it appears that this issue is dependent on the use of manually-set passwords that causes delays when processing /etc/shadow due to an increased number of rounds.
