Squirrelmail several remote vulnerabilities

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. Vicente Aguilera of Internet Security Auditors, S.L. discovered a CRLF injection vulnerability, which allows remote attackers to inject arbitrary IMAP commands.

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:

CVE-2006-0188

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.

CVE-2006-0195

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.

CVE-2006-0377

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
