Debian LTS: DLA-1936-1: cups security update
Summary
While generating a session cookie for the CUPS web interface, a
predictable random number seed was used. This could lead to unauthorized
scripted access to the enabled web interface.
For Debian 8 "Jessie",
this problem has been fixed in version 1.7.5-11+deb8u6.
We recommend that you upgrade your cups packages.
