Synopsis
The remote SSH server is affected by multiple vulnerabilities.Description
According to its banner, the version of OpenSSH installed on the remote host is affected by multiple vulnerabilities :- A race condition exists that may allow an unauthenticated, remote attacker to crash the service or, on portable OpenSSH, possibly execute code on the affected host. Note that successful exploitation requires that GSSAPI authentication be enabled.
- A flaw exists that may allow an attacker to determine the validity of usernames on some platforms. Note that this issue requires that GSSAPI authentication be enabled.
- When SSH version 1 is used, an issue can be triggered via an SSH packet that contains duplicate blocks that could result in a loss of availability for the service.
- On Fedora Core 6 (and possibly other systems), an unspecified vulnerability in the linux_audit_record_event() function allows remote attackers to inject incorrect information into audit logs.
Solution
Upgrade to OpenSSH 4.4 or later.See Also
