Red Hat Linux: RHSA-2000:128-02 Critical: Slocate Heap Overflow

By using a carefully crafted database, a local user could overwrite some of slocate's internal structures, leading to a local group slocate compromise.. ` --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: New slocate packages available to fix local group slocate compromise Advisory ID: RHSA-2000:128-02 Issue date: 2000-12-19 Updated on: 2000-12-19 Product: Red Hat Linux Keywords: slocate heap overflow Cross references: --------------------------------------------------------------------- 1. Topic: New slocate packages are availble for Red Hat Linux 6.x and Red Hat Linux 7. These fix a problem with the database parsing code in slocate. (slocate was not shipped with Red Hat Linux prior to version 6.0, so earlier versions are not affected.) 2. Relevant releases/architectures: Red Hat Linux 6.0 - alpha, i386, sparc Red Hat Linux 6.1 - alpha, i386, sparc Red Hat Linux 6.2 - alpha, i386, sparc Red Hat Linux 7.0 - alpha, i386 3. Problem description: A problem existed in the slocate database parsing code. By using a carefully crafted database, a local user could overwrite some of slocate's internal structures, leading to a local group slocate compromise. The affect of this compromise is that users could read the entire slocate database, and therefore learn the locations of files that they normally would not have permissions to locate.

Solution: For each RPM for your particular architecture, run: rpm -Fvh [filename] where filename is the name of the RPM. 5. Bug IDs fixed ( for more info): 21388 - heap corruption vulnerability 6. RPMs required: Red Hat Linux 6.0: SRPMS: alpha: i386: sparc: Red Hat Linux 6.1: SRPMS: alpha: i386: sparc: Red Hat Linux 6.2: SRPMS: alpha: i386: sparc: Red HatLinux 7.0: SRPMS: alpha: i386: 7.
