-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ Linux-Mandrake Security Update Advisory ________________________________________________________________________ Package name: pam Date: August 1st, 2000 Advisory ID: MDKSA-2000:029 Affected versions: 6.0, 6.1, 7.0, 7.1 ________________________________________________________________________ Problem Description: There is a problem with the pam_console module that incorrectly identifies remote X logins for displays other than :0 (for example, :1, :2, etc.) as being local displays, thus giving control of the console to the remote user. Because the remote user has control of the console they are able to issue commands to reboot the remote system after providing their password. Please note that this vulnerability is only exploitable if the system is running a graphical login manager like gdm, kdm, or xdm and if XDMCP is enabled and remote access is granted. Users are highly recommended to upgrade to this version which fixes the exploit (thanks to RedHat). ________________________________________________________________________ Please verify these md5 checksums of the updates prior to upgrading to ensure the integrity of the downloaded package. You can do this by running the md5sum program on the downloaded package by using "md5sum package.rpm".
