0.012 Low




Debian Security Advisory DSA 988-1 [email protected] Moritz Muehlenhoff
March 8th, 2006

Package : squirrelmail
Vulnerability : several
Problem-Type : remote
Debian-specific: no
CVE IDs : CVE-2006-0377 CVE-2006-0195 CVE-2006-0188
Debian Bug : 354062 354063 354064 355424

Several vulnerabilities have been discovered in Squirrelmail, a
commonly used webmail system. The Common Vulnerabilities and
Exposures project identifies the following problems:


Martijn Brinkers and Ben Maurer found a flaw in webmail.php that
allows remote attackers to inject arbitrary web pages into the right
frame via a URL in the right_frame parameter.


Martijn Brinkers and Scott Hughes discovered an interpretation
conflict in the MagicHTML filter that allows remote attackers to
conduct cross-site scripting (XSS) attacks via style sheet
specifiers with invalid (1) "/*" and "*/" comments, or (2) slashes
inside the "url" keyword, which is processed by some web browsers
including Internet Explorer.


Vicente Aguilera of Internet Security Auditors, S.L. discovered a
CRLF injection vulnerability, which allows remote attackers to
inject arbitrary IMAP commands via newline characters in the mailbox
parameter of the sqimap_mailbox_select command, aka "IMAP
injection." There's no known way to exploit this yet.

For the old stable distribution (woody) these problems have been fixed in
version 1.2.6-5.

For the stable distribution (sarge) these problems have been fixed in
version 2:1.4.4-8.

For the unstable distribution (sid) these problems have been fixed in
version 2:1.4.6-1.

We recommend that you upgrade your squirrelmail package.
