Certain versions of IRIX ship with a version libgl.so which is vulnerable to buffer overflow attacks. This library, libgl.so, is used in conjunction with graphical programs which use OpenGL. As a result a number of programs which utilize libgl.so can be exploited via this problem. The exploit which is in known public circulation at this time uses both gmemusage and gr_osview to exploit this problem. The buffer overflow itself is in how libgl.so handles the $HOME variable is handled (it is not checked for length). Further the programs which receive this $HOME variable from libgl.so further fail to limit it's size resulting in a buffer overflow attack. Should the receiving programs be SUID root (as are both gr_osview and gmemusage) the attacker will gain root access.
