More information:

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.
