TurboLinux Security Announcement
Package: kernel-2.2.15 and earlier
Date: Monday June 19 17:45 PDT 2000
Affected TurboLinux versions: 6.0.5 and earlier Vulnerability
Type: local root compromise TurboLinux Advisory ID#:
TLSA2000013-1 BugTraq ID#: 1322 Credits: This vulnerability
was discovered by Wojciech Purczynski.
___________________________________________________________________________
A security hole was discovered in the package mentioned above.
Please update the package in your installation as soon as possible.
___________________________________________________________________________
1. Problem Summary
Originally this security bug was reported by Sendmail. An unsafe
fgets() usage in sendmail's mail.local exposes the setuid()
security hole in the Linux kernel. This vunlnerability allows
local users to obtain root privilege by exploiting setuid root
applications.
2. Impact
Any local user with an account can use this vulnerability to obtain
root priviledges by exploiting setuid root applications.
3. a) Solution
Please read section 3. b) if you use "TurboLinux Data Server with
DB2" or "TurboLinux Data Server Optimized for Oracle 8i".
Update the packages from our ftp server by running the following
command for each package:
rpm -Uvh --nodeps --Force ftp_path_to_filename
Where ftp_path_to_filename is one of the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/kernel-2.2.16-0.4.i386.rpm

386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/kernel-2.2.16-0.4.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.
