TurboLinux Security Announcement
Package: glibc-2.1.2-17 and earlier
Date: Friday September 08 17:08 PDT 2000
Affected TurboLinux versions: 6.0.5 and earlier
TurboLinux Advisory ID#: TLSA2000021-1
___________________________________________________________________________
A security hole was discovered in the package mentioned above.
Please update the package in your installation as soon as possible.
___________________________________________________________________________
1. Problem Summary
There have been two major security vulnerabilities involving
glibc, one involving ld.so and unsetenv that allows local user's
to gain root privileges due to environment variables not getting
cleared out in some circumstances. Another vulnerability is lack
of good checking on the locale file specification which can be
set to a file provided by an attacker to crash an application and
gain root access. The locale problem is fully described in GNATS
PR 1883
http://www-gnats.gnu.org:8080/cgi-bin/wwwgnats.pl/full/1883.
2. Impact
These problems provide means for local users gain root privilege
on a system.
3. Solution
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 the following:
for 6.0.4 and up (glibc-2.1.2-17):
ftp://ftp.turbolinux.com/pub/updates/6.0/glibc-2.1.2-17S.i386.rpm
for 6.0 - 6.0.2 (glibc-2.1.2-15):
ftp://ftp.turbolinux.com/pub/updates/6.0/glibc-2.1.2-15S.i386.rpm
The source RPMs can be downloaded here:
for 6.0.4 and up (glibc-2.1.2-17):
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/glibc-2.1.2-17S.src.rpm
for 6.0 - 6.0.2 (glibc-2.1.2-15):
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/glibc-2.1.2-15S.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:
