Shortly after the release of SquirrelMail 1.4.10, a regression in the compose
form was discovered. Unfortunately the limited disclosure of security patches
does not allow for public testing, so this regression went unnoticed. We're
sorry for the inconvenience.
This version, 1.4.10 is a maintenance release, addressing
the following problems since 1.4.9a:
- Some security fixes (see below)
- Small enhancements
- A collection of bugfixes and stability enhancements
(see ChangeLog for a full list)
Security issues
===============
This release addresses security issues found since the release of 1.4.9a:
There's an ongoing battle to further secure the HTML filter against malicious
HTML mail and the browsers that accept almost any malformed piece of HTML.
This release contains fixes for the following:
- HTML attachments containing "data:" URLs;
- Internet Explorer in various versions accepts many permutations of HTML
and JavaScript in many charsets. We now properly canonicalize the incoming
HTML to us-ascii before applying further filters. IE only.
- Request forgery through images. It was possible to include "images" in
HTML mails which were in fact GET requests for the compose.php page sending
mail. These images are now properly detected, and the compose form will only
send mail through a POST request.
Thanks to Mikhail Markin, Tomas Kuliavas and Michael Jordon for reporting
(parts of) these issues and working with us to get them resolved.
These are known as CVE-2007-1262. Further details on SquirrelMail

and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
all PEAR packages to php?-pear-* and all Apache packages to ap13-* or
ap2-* respectively. Add new variables to simplify the Makefile
handling. Add CONFLICTS on the old names. Reset revisions of bumped
packages. ap-php will now depend on the default Apache and PHP version.
All programs using it have an implicit option of the Apache version
as well.
OK from jlam@ and adrianp@.
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
This release is very important, and we strongly advise everybody to
update to the latest release.
Security Update
===============
This version contains a number of security updates that were brought
to our attention via a number of sources.
- In webmail.php, the right_frame parameter was not properly sanitized
to deal with very lenient browsers, which allowed for cross site
scripting or frame replacing. [CVE-2006-0188]
- In the MagicHTML function, some very obscure constructs were
discovered to be exploitable: 'u\rl' was interpreted as 'url' (privacy
concern), and comments could be inside keywords (allows for cross site
scripting). Both only affect Internet Explorer users. Found by Martijn
Brinkers and Scott Hughes. [CVE-2006-0195]
- The function sqimap_mailbox_select did not strip newlines from the
mailbox parameter, and thereby allowed for IMAP command injection.
Found by Vicente Aguilera. [CVE-2006-0377]
"find foo -exec bar {} \;" while here, the former is faster, but can't
cope with all quoting issues and is also more likely to hit argument
length limits. CONFLICT to ja-squirrelmail.
