[Secure-testing-team] Bug#656278: t1lib: [PATCH] fixes for remaining CVEs

[Jamie Strandboge]

Package: t1lib
Version: 5.1.2-3.4
Severity: grave
Tags: patch security
Justification: user security hole

Dear Maintainer,

In Ubuntu, the attached patch was applied to achieve the following:

  * SECURITY UPDATE: fix denial of service via oversized fonts
    - debian/patches/CVE-2011-1552_1553_1554.patch: add additional tests to
      address remaining crashes
    - CVE-2011-1552
    - CVE-2011-1553
    - CVE-2011-1554
  * SECURITY UPDATE: fix heap-based buffer overflow via AFM font parser
    - update debian/patches/series to apply CVE-2010-2642.patch which was
      mistakenly not updated in 5.1.2-3.4
    - CVE-2010-2642
    - CVE-2011-0433


Debian took the Ubuntu patch for CVE-2011-0764 (which is great). RedHat
later fixed the remaining open CVEs with a patch landing in Fedora's
http://koji.fedoraproject.org/koji/buildinfo?buildID=282529. I then
verified all the patches in Debian against Fedora's patchset and came up
with this patch against 5.1.2-3.4. While Debian included an equivalent
patch for CVE-2010-2642 (which also fixes CVE-2011-0433), it was not
added to the debian/patches/series file, so it wasn't applied during the
build. The attached debdiff should bring unstable up to date on these
issues.

Thanks for considering the patch.
