"Several issues have been discovered by Unrud in Radicale, a calendar
and addressbook server. A remote attacker could exploit these
vulnerabilities and call arbitrary functions by sending crafted HTTP
requests.

CVE-2015-8748   Prevent regex injection in rights management.
  Prevent crafted HTTP request from calling arbitrary functions.

CVE-2015-8747   The multifilesystem backend allows access to
arbitrary files on all platforms. (Squeeze is not affected because the
multifilesystem backend does not exist in this version.)

For Debian 6 'Squeeze', these problems have been fixed in version
0.3-2+deb6u1.

We recommend that you upgrade your radicale packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
