Debian: DSA-4189-1 Moderate: Quassel Arbitrary Code Execution Risk

Two vulnerabilities were found in the Quassel IRC client, which could
result in the execution of arbitrary code or denial of service.

Note that you need to restart the 'quasselcore' service after upgrading
the Quassel packages.

For the oldstable distribution (jessie), these problems have been fixed
in version 1:0.10.0-2.3+deb8u4.

For the stable distribution (stretch), these problems have been fixed in
version 1:0.12.4-2+deb9u1.

We recommend that you upgrade your quassel packages.
