[Bug 911436] Re: https crashed with SIGSEGV in lookup_or_create_bucket()

[Launchpad Bug Tracker]

This bug was fixed in the package p11-kit - 0.12-2ubuntu1

---------------
p11-kit (0.12-2ubuntu1) precise; urgency=low

  * Merge with Debian, bringing in upstream module and build fixes.
  * Add valid-config-files.patch, introducing a static function to
    validate config filenames against a sane pattern (LP: #911436)
  * Add duplicate-module-fix.patch, making sure that after we unload
    a duplicate module, we stop trying to reference it (LP: #911436)

p11-kit (0.12-2) unstable; urgency=low

  * Upload to unstable.

p11-kit (0.12-1) experimental; urgency=low

  * Drop DEB_CPPFLAGS_MAINT_APPEND = -D_XOPEN_SOURCE=600 -D_BSD_SOURCE,
    upstream's usage of AC_USE_SYSTEM_EXTENSIONS should make this unnecessary.
  * Upload to experimental, let 0.11-3 propagate to wheezy.

p11-kit (0.11-3) unstable; urgency=low

  * Do not export CPPFLAGS in debian/rules, it disabled the respective
    hardening-options. (Thanks, Simon Ruderich) Closes: #662100

p11-kit (0.11-2) unstable; urgency=low

  * Bump versioning of p11_kit_initialize_registered,
    p11_kit_initialize_module and p11_kit_load_initialize_module.
    (Due to upstream change "Remove automatic reinitialization of PKCS#11
    after fork")
  * Use debhelper v9 compat to get dpkg-buildflags. Drop --libdir argument to
    ./configure, bump b-d.

p11-kit (0.11-1) unstable; urgency=low

  * New upstream version.

  https crashed with SIGSEGV in lookup_or_create_bucket()

  Fix Released

Bug description:
  This happened after a slightly broken upgrade, but it can be
  reproduced with

  $ sudo cp /etc/pkcs11/modules/gnome-keyring-module /etc/pkcs11/modules/gnome-keyring-module.dpkg-new
  $ sudo apt-get update
  p11-kit: duplicate configured module: gnome-keyring-module: /usr/lib/x86_64-linux-gnu/pkcs11/gnome-keyring-pkcs11.so
  E: Method https has died unexpectedly!
  E: Sub-process https received a segmentation fault.

  There are two bugs here, I suppose.  One is that pkcs11 should ignore
  *.dpkg-new files (usually this would be done by reading, e.g.,
  /etc/pkcs11/modules/*.conf instead of /etc/pkcs11/modules/*), and the
  other is that a duplicate file shouldn’t cause a crash.
