Description:
SGI has issued an update for BSD LPR. This fixes multiple older vulnerabilities and one recent vulnerability.
One vulnerability allows malicious users to bypass hostname based security due to an error in the "chkhost()" function. This can be exploited to print from unauthorised hosts.
Another vulnerability allows malicious users to pass arguments to the sendmail binary. This could be exploited to gain root access.
The newer vulnerability allows local users to cause a buffer overflow in "lprm". This can be exploited to escalate privileges to root.
Solution:
Version 6.5.20 is not vulnerable.
For versions 6.5.14 to 6.5.19 apply patch number 5071 from:
ftp://patches.sgi.com/support/free/security/patches/
Changelog:
2003-04-25: SGI reported that the original patch did not fix all of the vulnerabilities. New patch released.
