Red Hat Enterprise Linux (RHEL) 5 ships the rpm for the Advanced Intrusion Detection Environment (AIDE) before 0.13.1 with a database that lacks checksum information, which allows context-dependent attackers to bypass file integrity checks and modify certain files.

The remote Oracle Linux 5 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2007-0539 advisory.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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.

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.

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.
