Technical details
A buffer overflow vulnerability exists in the /usr/sbin/printers executable in SGI IRIX. The flaw is triggered via the -xrm command-line argument, which fails to properly validate the length of input data before copying it into a fixed-size buffer. A local attacker can exploit this by passing a specially crafted, overly long string to the program, allowing them to overwrite the return address on the stack and redirect execution to an attacker-supplied shellcode. Successful exploitation results in arbitrary code execution with root privileges. The vulnerability has been confirmed on IRIX versions 5.3, 6.2, and 6.3.
