[Marco Ivaldi <marco.ivaldi () mediaservice net>]

Dear Bugtraq,

Please find attached an advisory for the following vulnerability, fixed in Oracle's Critical Patch Update (CPU) of 
October 2019:

"Exploitation of a design error vulnerability in xscreensaver, as distributed with Solaris 11.x, allows local attackers 
to create (or append to) arbitrary files on the system, by abusing the -log command line switch introduced in version 
5.06. This flaw can be leveraged to cause a denial of service condition or to escalate privileges to root."
