Evolution 2.22.3.1 checks S/MIME signatures against a copy of the e-mail text within a signed-data blob, not the copy of the e-mail text displayed to the user, which allows remote attackers to spoof a signature by modifying the latter copy, a different vulnerability than CVE-2008-5077.

From Red Hat Security Advisory 2009:0355 :

Updated evolution and evolution-data-server packages that fixes multiple security issues are now available for Red Hat Enterprise Linux 4.

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

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

Evolution Data Server provides a unified back-end for applications which interact with contacts, task and calendar information. Evolution Data Server was originally developed as a back-end for Evolution, but is now used by multiple other applications.

Evolution 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 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)

Multiple integer overflow flaws which could cause heap-based buffer overflows were found in the Base64 encoding routines used by evolution and evolution-data-server. This could cause evolution, or an application using evolution-data-server, to crash, or, possibly, execute an arbitrary code when large untrusted data blocks were Base64-encoded. (CVE-2009-0587)

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

The following bugs have been fixed :

evolution considered S/MIME signatures to be valid even for modified mails (CVE-2009-0547). specially crafted base64 encoded messages could cause a heap buffer overflow (CVE-2009-0587). A POP3 server sending overly long lines could crash evolution.

evolution considered S/MIME signatures to be valid even for modified mails (CVE-2009-0547).

This update fixes the following vulnerability :

evolution considered S/MIME signatures to be valid even for modified mails. (CVE-2009-0547: CVSS v2 Base Score: 5.0)

Additionally the following bug has been fixed :

  - A POP3 server sending overly long lines could crash     evolution.

Several vulnerabilities have been found in evolution-data-server, the database backend server for the evolution groupware suite. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-0587     It was discovered that evolution-data-server is prone to     integer overflows triggered by large base64 strings.

  - CVE-2009-0547     Joachim Breitner discovered that S/MIME signatures are     not verified properly, which can lead to spoofing     attacks.

  - CVE-2009-0582     It was discovered that NTLM authentication challenge     packets are not validated properly when using the NTLM     authentication method, which could lead to an     information disclosure or a denial of service.

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A wrong handling of signed Secure/Multipurpose Internet Mail Extensions (S/MIME) e-mail messages enables attackers to spoof its signatures by modifying the latter copy (CVE-2009-0547).

Crafted authentication challange packets (NT Lan Manager type 2) sent by a malicious remote mail server enables remote attackers either to cause denial of service and to read information from the process memory of the client (CVE-2009-0582).

Multiple integer overflows in Base64 encoding functions enables attackers either to cause denial of service and to execute arbitrary code (CVE-2009-0587).

This update provides fixes for those vulnerabilities.

Update :

evolution-data-server packages from Mandriva Linux distributions 2008.1 and 2009.0 are not affected by CVE-2009-0587.
