Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201001-08
(SquirrelMail: Multiple vulnerabilities)

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.
