Synopsis
=======
Multiple vulnerabilities were found in SquirrelMail of which the worst
results in remote code execution.
Background
=========
SquirrelMail is a standards-based webmail package written in PHP.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/squirrelmail < 1.4.19 >= 1.4.19
Description
==========
Multiple vulnerabilities were found in SquirrelMail:
* Niels Teusink reported multiple input sanitation flaws in certain
encrypted strings in e-mail headers, related to
contrib/decrypt_headers.php, PHP_SELF and the query string (aka
QUERY_STRING) (CVE-2009-1578).
* Niels Teusink also reported that the map_yp_alias() function in
functions/imap_general.php does not filter shell metacharacters in a
username and that the original patch was incomplete (CVE-2009-1381,
CVE-2009-1579).
* Tomas Hoger discovered an unspecified session fixation
vulnerability (CVE-2009-1580).
* Luc Beurton reported that functions/mime.php does not protect the
application's content from Cascading Style Sheets (CSS) positioning
in HTML e-mail messages (CVE-2009-1581).
Impact
=====
The vulnerabilities allow remote attackers to execute arbitrary code
with the privileges of the user running the web server, to hijack web
sessions via a crafted cookie, to spoof the user interface and to
conduct Cross-Site Scripting and phishing attacks, via a specially
crafted message.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All SquirrelMail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.19"
