Fedora 10: 2009-2784 Critical: Evolution Data Server Signature Spoofing

The evolution-data-server package provides a unified backend for programs that work

with contacts, tasks, and calendar information.

It was originally developed for Evolution (hence the name), but is now used

by other packages.

This update fixes two security issues: Evolution Data Server did not properly

check the Secure/Multipurpose Internet Mail Extensions (S/MIME) signatures used

for public key encryption and signing of e-mail messages. An attacker could use

this flaw to spoof a signature by modifying the text of the e-mail message

displayed to the user. (CVE-2009-0547) It was discovered that Evolution Data

Server did not properly validate NTLM (NT LAN Manager) authentication challenge

packets. A malicious server using NTLM authentication could cause an application

using Evolution Data Server to disclose portions of its memory or crash during

user authentication. (CVE-2009-0582)
