radicale - security update

Two vulnerabilities were fixed in radicale, a CardDAV/CalDAV server.

• CVE-2015-8747
  The (not configured by default and not available on Wheezy)
  multifilesystem storage backend allows read and write access to
  arbitrary files (still subject to the DAC permissions of the user
  the radicale server is running as).
• CVE-2015-8748
  If an attacker is able to authenticate with a user name like .\*', he can bypass read/write limitations imposed by regex-based rules, including the built-in rules owner_write’ (read for everybody,
  write for the calendar owner) and `owner_only’ (read and write for
  the the calendar owner).

For the oldstable distribution (wheezy), these problems have been fixed
in version 0.7-1.1+deb7u1.

For the stable distribution (jessie), these problems have been fixed in
version 0.9-1+deb8u1.

For the testing distribution (stretch), these problems have been fixed
in version 1.1.1-1.

For the unstable distribution (sid), these problems have been fixed in
version 1.1.1-1.

We recommend that you upgrade your radicale packages.
