Full Text Bug Listing

Description:
A security issue has been reported in Mozilla Firefox, which can be exploited
by malicious people to conduct cross-site scripting attacks.

The problem is that the "jar:" protocol handler does not validate the MIME type
of the contents of an archive, which are then executed in the context of the
site hosting the archive. This can be exploited to conduct cross-site scripting
attacks on sites that allow a user to upload certain files (e.g. .zip, .png,
.doc, .odt, .txt).

Solution:
Do not follow untrusted "jar:" links or browse untrusted websites.

Provided and/or discovered by:
Reported by Jesse Ruderman in a Bugzilla entry.

Independently discovered by pdp.

CVE-2007-5959 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-5959):
  Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.10 and
  SeaMonkey before 1.1.7 allow remote attackers to cause a denial of service
  (crash) and possibly execute arbitrary code via unknown vectors that trigger
  memory corruption.

CVE-2007-5960 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-5960):
  Mozilla Firefox before 2.0.0.10 and SeaMonkey 1.1.7 sets the Referer header
  to the window or frame in which script is running, instead of the address of
  the content that initiated the script, which allows remote attackers to spoof
  HTTP Referer headers and bypass Referer-based CSRF protection schemes by
  setting window.location and using a modal alert dialog that causes the wrong
  Referer to be sent.

Fixed in Firefox 2.0.0.10
MFSA 2007-39 Referer-spoofing via window.location race condition
MFSA 2007-38 Memory corruption vulnerabilities (rv:1.8.1.10)
MFSA 2007-37 jar: URI scheme XSS hazard

Mozilla herd, please advise.

2.0.0.10 contains a big regression:
https://bugzilla.mozilla.org/show_bug.cgi?id=405584

I'm working on it

The 2.0.0.10 ebuild already contains a fix for the regression mentioned by
Raul.

Arches, please test and mark stable www-client/mozilla-firefox-2.0.0.10.

Fixes for -bin and seamonkey will follow.

Stable for HPPA.

Security please stabilize 2.0.0.11 instead, since it corrects a very important
bug rbu already knows. -bin and not-bin should be in the tree soon.

Arches, please test and mark stable www-client/mozilla-firefox-2.0.0.11.

Already stabled : "alpha ia64 sparc x86"

Arches, please test and mark stable www-client/mozilla-firefox-bin-2.0.0.11.
Target keywords : "amd64 x86"

-bin stable on x86, someone else please test sources ;)

alpha/ia64/sparc/x86 stable

Please do =net-libs/xulrunner-1.8.1.11 as well, the distfile is in
dev.g.o:/space/distfiles-local

ppc64 stable

ppc stable

Stable for HPPA.

Done mozilla-firefox{-bin} for amd64, xulrunner to follow in the morning (GMT)

Ok, amd64's all done.

Readding HPPA as xulrunner isn't done yet.

=net-libs/xulrunner-1.8.1.11 stable for HPPA.

glsa time, we'll merge it with the seamonkey draft since it's the same CVE (bug
#200909)

mips done

GLSA 200712-20, thanks everyone.

Does not affect current (2008.0) release. Removing release.
