Updated evolution-data-server package that fixes a security bug are 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.

The evolution-data-server package provides a unified backend for programs that work with contacts, tasks, and calendar information.

A flaw was found in the way evolution-data-server processed certain APOP authentication requests. By sending certain responses when evolution-data-server attempted to authenticate against an APOP server, a remote attacker could potentially acquire certain portions of a user's authentication credentials. (CVE-2007-1558)

All users of evolution-data-server should upgrade to these updated packages, which contain a backported patch which resolves this issue.

From Red Hat Security Advisory 2007:0401 :

Updated thunderbird packages that fix several security bugs are now available for Red Hat Enterprise Linux 4 and 5.

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

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the way Thunderbird processed certain malformed JavaScript code. A web page containing malicious JavaScript code could cause Thunderbird to crash or potentially execute arbitrary code as the user running Thunderbird. (CVE-2007-2867, CVE-2007-2868)

Several denial of service flaws were found in the way Thunderbird handled certain form and cookie data. A malicious website that is able to set arbitrary form and cookie data could prevent Thunderbird from functioning properly. (CVE-2007-1362, CVE-2007-2869)

A flaw was found in the way Thunderbird processed certain APOP authentication requests. By sending certain responses when Thunderbird attempted to authenticate against an APOP server, a remote attacker could potentially acquire certain portions of a user's authentication credentials. (CVE-2007-1558)

A flaw was found in the way Thunderbird displayed certain web content.
A malicious web page could generate content which could overlay user interface elements such as the hostname and security indicators, tricking users into thinking they are visiting a different site.
(CVE-2007-2871)

Users of Thunderbird are advised to apply this update, which contains Thunderbird version 1.5.0.12 that corrects these issues.

The remote host is affected by the vulnerability described in GLSA-200706-06 (Mozilla products: Multiple vulnerabilities)

    Mozilla developers fixed several bugs involving memory corruption     through various vectors (CVE-2007-2867, CVE-2007-2868). Additionally,     several errors leading to crash, memory exhaustion or CPU consumption     were fixed (CVE-2007-1362, CVE-2007-2869). Finally, errors related to     the APOP protocol (CVE-2007-1558), XSS prevention (CVE-2007-2870) and     spoofing prevention (CVE-2007-2871) were fixed.
  Impact :

    A remote attacker could entice a user to view a specially crafted web     page that will trigger one of the vulnerabilities, possibly leading to     the execution of arbitrary code or a Denial of Service. It is also     possible for an attacker to spoof the address bar or other browser     elements, obtain sensitive APOP information, or perform cross-site     scripting attacks, leading to the exposure of sensitive information,     like user credentials.
  Workaround :

    There is no known workaround at this time.

This update brings Mozilla SeaMonkey to security update version 1.1.2

  - MFSA 2007-17 / CVE-2007-2871 :

    Chris Thomas demonstrated that XUL popups opened by web     content could be placed outside the boundaries of the     content area. This could be used to spoof or hide parts     of the browser chrome such as the location bar.

  - MFSA 2007-16 / CVE-2007-2870 :

    Mozilla contributor moz_bug_r_a4 demonstrated that the     addEventListener method could be used to inject script     into another site in violation of the browser's     same-origin policy. This could be used to access or     modify private or valuable information from that other     site.

  - MFSA 2007-15 / CVE-2007-1558 :

    Ga&iuml;&iquest;&frac12;tan Leurent informed us of a     weakness in APOP authentication that could allow an     attacker to recover the first part of your mail password     if the attacker could interpose a malicious mail server     on your network masquerading as your legitimate mail     server. With normal settings it could take several hours     for the attacker to gather enough data to recover just a     few characters of the password. This result was     presented at the Fast Software Encryption 2007     conference. 

  - MFSA 2007-14 / CVE-2007-1362 :

    Nicolas Derouet reported two problems with cookie     handling in Mozilla clients. Insufficient length checks     could be use to exhaust browser memory and so to crash     the browser or at least slow it done by a large degree.

    The second issue was that the cookie path and name     values were not checked for the presence of the     delimiter used for internal cookie storage, and if     present this confused future interpretation of the     cookie data. This is not considered to be exploitable.

  - MFSA 2007-13 / CVE-2007-2869 :

    Marcel reported that a malicious web page could perform     a denial of service attack against the form autocomplete     feature that would persist from session to session until     the malicious form data was deleted. Filling a text     field with millions of characters and submitting the     form will cause the victim's browser to hang for up to     several minutes while the form data is read, and this     will happen the first time autocomplete is triggered     after every browser restart. 

    No harm is done to the user's computer, but the     frustration caused by the hang could prevent use of     Thunderbird if users don't know how to clear the bad     state.

  - MFSA 2007-12 / CVE-2007-2867 / CVE-2007-2868

    As part of the Thunderbird 2.0.0.4 and 1.5.0.12 update     releases Mozilla developers fixed many bugs to improve     the stability of the product. Some of these crashes that     showed evidence of memory corruption under certain     circumstances and we presume that with enough effort at     least some of these could be exploited to run arbitrary     code. 

    Without further investigation we cannot rule out the     possibility that for some of these an attacker might be     able to prepare memory for exploitation through some     means other than JavaScript, such as large images.

  - MFSA 2007-11 / CVE-2007-1562 :

    Incorrect FTP PASV handling could be used by malicious     ftp servers to do a rudimentary port scanning of for     instance internal networks of the computer the browser     is running on.

The remote version of Mozilla Thunderbird suffers from various security issues, at least one of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

The installed version of SeaMonkey contains various security issues, one of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.
