Solaris bug gives hackers free rein

Author: JT Smith

ZDNet UK: "Researchers have discovered a bug that could give hackers unlimited access to any machine
running Sun's Unix operating system, Solaris.

The bug, discovered by security consultancy ISS X-Force, affects a utility designed to give remote
users access to a local printer. The line printer daemon (in.lpd), as it is called, contains a flaw in the
"transfer job" routine that could allow hackers to overflow an unchecked buffer, a common means of
gaining unauthorised access to a computer."
