Synopsis

An integer underflow vulnerability has been reported in The Sleuth Kit allowing for the user-assisted execution of arbitrary code.

2. Impact Information

Background

The Sleuth Kit is a collection of file system and media management forensic analysis tools.

Description

Jean-Sebastien Guay-Leroux reported an integer underflow in the file_printf() function of the "file" utility which is bundled with The Sleuth Kit (CVE-2007-1536, GLSA 200703-26). Note that Gentoo is not affected by the improper fix for this vulnerability (identified as CVE-2007-2799, see GLSA 200705-25) since version 4.20 of "file" was never shipped with The Sleuth Kit ebuilds.

Impact

A remote attacker could entice a user to run The Sleuth Kit on a file system containing a specially crafted file that would trigger a heap-based buffer overflow possibly leading to the execution of arbitrary code with the rights of the user running The Sleuth Kit.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All The Sleuth Kit users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-forensics/sleuthkit-2.0.9"
