>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.
>
> Please verify the MD5 checksums of the updates before you install:
>
> MD5 sum Package Name
