Problem description

An input validation error exists in the OpenSSH server between versions 2.3.1 and 3.3 that can result in an integer overflow and privilege escalation. This error is found in the PAMAuthenticationViaKbdInt code in versions 2.3.1 to 3.3, and the ChallengeResponseAuthentication code in versions 2.9.9 to 3.3. OpenSSH 3.4 and later are not affected, and OpenSSH 3.2 and later prevent privilege escalation if UsePrivilegeSeparation is enabled; in OpenSSH 3.3 and higher this is the default behaviour of OpenSSH. To protect yourself, users should be using OpenSSH 3.3 with UsePrivilegeSeparation enabled (see MDKSA:2002-040). However, it is highly recommended that all Mandrake Linux users upgrade to version 3.4 which corrects these errors. There are a few caveats with this upgrade, however, that users should be aware of: - On Linux kernel 2.2 (the default for Mandrake Linux 7.x), the use of Compression and UsePrivilegeSeparation are mutually exclusive. You can use one feature or the other, not both; we recommend disabling Compression and using privsep until this can be resolved. - Using privsep may cause some PAM modules which expect to run with root privilege to fail. For instance, users will not be able to change their password if they attempt to log into an account with an expired password. If you absolutely must use one of these features that conflict with privsep, you can disable it in /etc/ssh/sshd_config by using: UsePrivilegeSeparation no However, if you do this, be sure you are running OpenSSH 3.4. Updates to OpenSSH will be made available once these problems are resolved.
