Silicon Graphics Inc. has investigated the issue and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL SGI systems. This issue will be corrected in future releases of IRIX. - -------------- - --- Impact --- - -------------- All Silicon Graphics computer systems running IRIX 4.x, IRIX 5.x and IRIX 6.x utilize the X Windowing system and have X applications by default. A local account is required in order to exploit these vulnerabilities both locally and remotely. This issue has been publically disclosed and discussed in several public forums newsgroups and mailing lists in addition to security advisories CERT CA-97.11. - -------------------------- - --- Temporary Solution --- - -------------------------- Unfortunately, there are no immediate or temporary workarounds for this issue. The issue can only be addressed with a patch. - ---------------- - --- Solution --- - ---------------- OS Version Vulnerable?
