Updated slocate packages are now available that fix vulnerabilities allowing a local user to gain "slocate" group privileges.
Slocate is a security-enhanced version of locate, designed to find files on a system via a central database. Patrik Hornik discovered a vulnerability in Slocate versions up to and including 2.7 where a carefully crafted database could overflow a heap-based buffer. A local user could exploit this vulnerability to gain "slocate" group privileges and then read the entire slocate database. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0848 to this issue. Users of Slocate should upgrade to these erratum packages, which contain Slocate version 2.7 with the addition of a patch from Kevin Lindsay that causes slocate to drop privileges before reading a user-supplied database. For CentOS Linux 2.1 these packages also fix a buffer overflow that affected unpatched versions of Slocate prior to 2.7. This vulnerability could also allow a local user to gain "slocate" group privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0056 to this issue.
