Please update the package in your installation as soon as possible. ___________________________________________________________________________ 1. Problem Summary Sendmail, launched with the -bt command-line switch, enters its special "address test" mode. Under these conditions, it is vulnerable to a segmentation fault which can occur when trying to set a class in ad- dress test mode due to a negative array index. 2. Impact A user can gain root privileges. 3. Solution Update the package from our ftp server by running the following command: rpm -Uvh ftp_path_to_filename Where ftp_path_to_filename is the following: ftp://ftp.turbolinux.com/pub/updates/6.0/security/sendmail-8.11.2-5.i386.rpm The source RPM can be downloaded here: ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/sendmail-8.11.2-5.src.rpm **Note: You must rebuild and install the RPM if you choose to download and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE THE SECURITY HOLE.
