IRIX is a Unix operating system used primarily on Sun workstations. The libgl.so library is part of the IRIX graphics stack, providing access to graphics and display functionality. A buffer overflow in this library allows local users to gain root privileges by manipulating the HOME variable in programs like gmemusage and gr_osview.
You're affected if you use Irix version 5.3 or earlier. Check with: grep "libgl.so" /usr/lib/irix/libc.a
Note: This CVE is specific to Irix, which was a proprietary Unix operating system. If you don't recognize the name, you're probably not affected.
Upgrade to Irix version 5.4 or later.
