Title: IRIX inpview Race Condition Vulnerability
Severity: MODERATE
Description:
Certain versions of IRIX ship with a version of inpview that creates files in '/var/tmp/' in an insecure manner and is therefore prone to a race condition.
InPerson's 'inpview' is a networked multimedia conferencing tool. InPerson provides multiway audio and video conferencing with a shared whiteboard, combined into a single, easy-to-use application. You use a separate "phone" tool to place and answer calls.
The 'inpview' program writes out temporary files in the '/var/tmp' directory. Because these filenames are not random, an attacker can create a symlink to a previously created filename and force the SUID 'inpview' to overwrite the file with 'rw-rw-rw' permissions.
