Synopsis

Moderate: evolution security update

Type/Severity

Security Advisory Moderate

Topic

Updated evolution packages that fixes multiple security issues are now available for Red Hat Enterprise Linux 3.

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

Description

Evolution is the integrated collection of e-mail, calendaring, contact management, communications, and personal information management (PIM) tools for the GNOME desktop environment.

It was discovered that evolution did not properly validate NTLM (NT LAN Manager) authentication challenge packets. A malicious server using NTLM authentication could cause evolution to disclose portions of its memory or crash during user authentication. (CVE-2009-0582)

An integer overflow flaw which could cause heap-based buffer overflow was found in the Base64 encoding routine used by evolution. This could cause evolution to crash, or, possibly, execute an arbitrary code when large untrusted data blocks were Base64-encoded. (CVE-2009-0587)

All users of evolution are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running instances of evolution must be restarted for the update to take effect.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
