Solaris hole gives hackers free rein By Matthew Broersma, ZDNet News June 22, 2001 URL: http://www.zdnet.com.au/news/soa/Solaris-hole-gives-hackers-free-rein/0,139023165,120233977,00.htm
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. Hackers could exploit the flaw to crash the printer daemon or execute malicious code with system administrator privileges, according to X-Force. The printer software is installed by default on all Solaris systems. Sun says it is working on a fix, which will be available next month, and X-Force recommends the software be turned off until the patch is available. Solaris runs on Sun Microsystems and Intel hardware, and is the dominant operating system for high-end Internet servers.
