Red Hat Security Advisory
Synopsis: Important: squirrelmail security update
Advisory ID: RHSA-2009:1066-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1066.html
Issue date: 2009-05-26
CVE Names: CVE-2009-1578 CVE-2009-1579 CVE-2009-1581
=====================================================================
1. Summary:
An updated squirrelmail package that fixes multiple security issues is now
available for Red Hat Enterprise Linux 3, 4, and 5.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - noarch
Red Hat Desktop version 3 - noarch
Red Hat Enterprise Linux ES version 3 - noarch
Red Hat Enterprise Linux WS version 3 - noarch
Red Hat Enterprise Linux AS version 4 - noarch
Red Hat Enterprise Linux Desktop version 4 - noarch
Red Hat Enterprise Linux ES version 4 - noarch
Red Hat Enterprise Linux WS version 4 - noarch
RHEL Desktop Workstation (v. 5 client) - noarch
Red Hat Enterprise Linux (v. 5 server) - noarch
3. Description:
SquirrelMail is a standards-based webmail package written in PHP.
A server-side code injection flaw was found in the SquirrelMail
"map_yp_alias" function. If SquirrelMail was configured to retrieve a
user's IMAP server address from a Network Information Service (NIS) server
via the "map_yp_alias" function, an unauthenticated, remote attacker using
a specially-crafted username could use this flaw to execute arbitrary code
with the privileges of the web server. (CVE-2009-1579)
Multiple cross-site scripting (XSS) flaws were found in SquirrelMail. An
attacker could construct a carefully crafted URL, which once visited by an
unsuspecting user, could cause the user's web browser to execute malicious
script in the context of the visited SquirrelMail web page. (CVE-2009-1578)
It was discovered that SquirrelMail did not properly sanitize Cascading
Style Sheets (CSS) directives used in HTML mail. A remote attacker could
send a specially-crafted email that could place mail content above
SquirrelMail's controls, possibly allowing phishing and cross-site
scripting attacks. (CVE-2009-1581)
Users of squirrelmail should upgrade to this updated package, which
contains backported patches to correct these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
