SGI has investigated the issue and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL vulnerable SGI systems. These issues have been corrected in IRIX 6.5.12 and later versions. - -------------- - --- Impact --- - -------------- The /usr/etc/netstat binary is part of the IRIX base system, and is installed by default on all SGI machines.

SGI is not aware of any specific exploits for this, but this ability could conceivably be used for nefarious purposes. This vulnerability may be not exploited by a remote user, a local account is required. This vulnerability has been fixed in IRIX 6.5.12 and later versions. This vulnerability was assigned the following CVE: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0355 - ---------------------------- - --- Temporary Workaround --- - ---------------------------- There is no effective workaround for this vulnerability.
