Red Hat, Inc. Security Advisory Synopsis: glint symlink vulnerability Advisory ID: RHSA-2000:062-03 Issue date: 2000-09-19 Updated on: 2000-09-19 Product: Red Hat Linux Keywords: glint symlink rpm Cross references: N/A
glint blindly follows a symlink in /tmp, overwriting the target file, so it can conceivably be used to destroy any file on the system.
2. Relevant releases/architectures:
Red Hat Linux 5.2 - i386, alpha, sparc
3. Problem description:
If a specific symlink exists in /tmp, glint will open it and write to it when run by root -- so destruction of any file is possible.
Note that glint does not work with RPM 3.0 or higher. If you have RPM 3.0 or higher installed, just uninstall the glint package to remove this vulnerability.
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
17544 - HUGE race condition in Glint
6. RPMs required:
Red Hat Linux 5.2:
