TurboLinux Security Announcement Vulnerable Packages: slocate-2.3-1 and earlier Date: 02/02/2001 5:00 PDT Affected TurboLinux versions:TL 6.1 WorkStation, All TurboLinux versions 6.0.5 and earlier TurboLinux Advisory ID#: TLSA2001002-1 Credits: Vulnerability discovered by zorgon Detailed information and exploit posted to Bugtraq by Michel Kaempf.
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 is a heap-corruption vulnerability existing in slocate. It can compromise slocate's ability to maintain an index of the entire file- system as well as its ability to read user-specified databases.
2. Impact(Based on the BugTraq advisory on securityfocus.com, id#2004)
Secure Locate maintains an index of the entire filesystem, including files only visible by root. The slocate binary is setgid "slocate" so it can read this index. The heap-corruption vulnerability may com- promise disclosure of these files if exploited.
When running slocate, users are able to specify a database of their own as a commandline parameter. A subtle vulnerability exists in slocate's reading of these user-supplied databases that may allow a local user to execute arbitrary code with effective gid slocate.
When reading the contents of the database file, slocate
initially reads a value from the file that is supposed to indicate
the offset in a
As a result, it is possible for a local user to overwrite internal malloc memory structures on the heap with arbitrary data. Attackers can replace a legitimate malloc structure with a malicious one designed to cause other areas of memory to be overwritten.
Update the package from our ftp server by running the following command:
rpm -Uvh --nodeps --force ftp_path_to_filename
Where ftp_path_to_filename is the following:
