RHSA-2007:0539 - Security Advisory

Topic

An updated aide package that fixes various bugs is now available for Red
Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

Advanced Intrusion Detection Environment (AIDE) is a file integrity checker
and intrusion detection program.

A flaw was discovered in the way file checksums were stored in the AIDE
database. A packaging flaw in the Red Hat AIDE rpm resulted in the file
database not containing any file checksum information. This could prevent
AIDE from detecting certain file modifications. (CVE-2007-3849)

This update also fixes the following bugs:

• certain configurations could result in a segmentation fault upon

initialization.

• AIDE was unable to open its log file in the LSPP evaluated configuration.
• if AIDE found SELinux context differences, the changed files report it

generated only included the first 32 characters of the context.

All users of AIDE are advised to upgrade to this updated package containing
AIDE version 0.13.1 which is not vulnerable to these issues.
