[Backports-security-announce] Security Update for xml-security-c

Russ Allbery uploaded new packages for xml-security-c which fixed the
following security problems:

CVE-2009-0217 (CERT VU#466161)

  It was discovered that the W3C XML Signature recommendation contains a
  protocol-level vulnerability related to HMAC output truncation.  This
  update implements the proposed workaround in the C++ version of the
  Apache implementation of this standard, xml-security-c, by preventing
  truncation to output strings shorter than 80 bits or half of the
  original HMAC output, whichever is greater.

For the etch-backports distribution the problems have been fixed in
version 1.4.0-4~bpo40+1. The binary packages are libxml-security-c14 and

For the squeeze and sid distributions the problems have been fixed in
version 1.4.0-4.

Upgrade instructions

If you don't use pinning (see [1]) you have to update the packages
manually via "apt-get -t etch-backports install <packagelist>" with the
packagelist of your installed packages affected by this update.

We recommend to pin the backports repository to 200 so that new versions
of installed  backports will be installed automatically:

  Package: *
  Pin: release a=etch-backports
  Pin-Priority: 200
