CVE-2006-5051: Race Condition

First published: Wed Sep 27 2006(Updated: )

OpenSSH 4.4 was released and mentions: * Fix an unsafe signal hander reported by Mark Dowd. The signal handler was vulnerable to a race condition that could be exploited to perform a pre-authentication denial of service. On portable OpenSSH, this vulnerability could theoretically lead to pre-authentication remote code execution if GSSAPI authentication is enabled, but the likelihood of successful exploitation appears remote. This could only affect RHEL4 as previous RHEL did not support GSSAPI
