TurboLinux Security Announcement
Package: OpenLDAP 1.2.9 and earlier
Date: Wed May 17 16:13:03 PDT 2000
Affected TurboLinux versions: 6.0.2 and earlier
Vulnerability Type: local users can destroy any file
TurboLinux Advisory ID#: TLSA2000010-1
BugTraq ID#: NA
Credits: This vulnerability was posted to Bugtraq in an
announcement by RedHat on April 22, 2000.
______________________________________________________________________________
A security hole was discovered in the packages mentioned above.
Please update the packages in your installation as soon as possible
or disable the service.
_____________________________________________________________________________
1. Problem Summary
From MandrakeSoft's excellent summary:
OpenLDAP follows symbolic links when creating files. The default
location for these files is /usr/tmp, which is a symlink to /tmp,
which in turn is a world-writable directory.
2. Impact
Local users can destroy the contents of any file on any mounted
filesystem.
3. Solution
Update the packages from our ftp server by running the following
command for EACH new openldap package (4 total):
rpm -Fvh ftp_path_to_filename
Where ftp_path_to_filename are the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/openldap-1.2.10-1.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/openldap-devel-1.2.10-1.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/openldap-libs-1.2.10-1.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/openldap-server-1.2.10-1.i386.rpm
The source rpm can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/openldap-1.2.10-1.src.rpm
**Note: You must rebuild and install the rpms if you choose to
download and install the srpm. Simply installing the srpm alone
WILL NOT CLOSE THE SECURITY HOLE.
Please verify the md5 checksum of the updates before you install:
MD5 sum Package Name
