The upgrade of IRIX on Origin 3000 to 6.5.13 through 6.5.16 changes the MAC address of the system, which could modify intended access restrictions that are based on a MAC address.
mv in IRIX 6.5 creates a directory with world-writable permissions while moving a directory, which could allow local users to modify files and directories.
Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391.
The dtterm terminal emulator allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands.
SGI IRIX 6.5 through 6.5.14 applies a umask of 022 to root core dumps, which allows local users to read the core dumps and possibly obtain sensitive information.
SGI IRIX 6.5 through 6.5.17 creates temporary desktop files with world-writable permissions, which allows local users to overwrite or corrupt those files.
