Subject: [TL-Security-Announce] openLDAP TLSA2000010-1
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
25c417d01c89ecb5a5e8690d2dee1d92 openldap-1.2.10-1.i386.rpm 0053d6ba1f2bb47dfe49673ab3a6ca5a openldap-devel-1.2.10-1.i386.rpm 106ec91d5acae8e60c227e64867aa335 openldap-libs-1.2.10-1.i386.rpm e04f082c50c08d51c6ec0f75361e3923 openldap-servers-1.2.10-1.i386.rpm fc7f1252ea654cb5a70b6cc7afea0a5d openldap-1.2.10-1.src.rpm
These packages are GPG signed by Turbolinux for security. Our key
is available here:
http://www.turbolinux.com/security/tlgpgkey.asc
To verify a package, use the following command:
rpm –checksig name_of_rpm
To examine only the md5sum, use the following command:
rpm –checksig –nogpg name_of_rpm
**Note: Checking GPG keys requires RPM 3.0 or higher.
