CVE-2006-5052
Unspecified vulnerability in portable OpenSSH before 4.4, when running on some platforms, allows remote attackers to determine the validity of usernames via unknown vectors involving a GSSAPI "authentication abort."
Does this matter?
Lower severity and a low EPSS score (2.91%). Track it; it rarely justifies an emergency change on its own.
