Debian DSA-3462-1 : radicale - security update

critical Nessus Plugin ID 88497

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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).

Solution

Upgrade the radicale packages.

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.
