- --------------------------BEGIN INCLUDED TEXT--------------------
IBM General Parallel File System denial-of-service vulnerability
More support for:
General Parallel File System
AIX, Linux, System x, Windows
A security vulnerability has been identified in GPFS v3.4 and v3.5 that
can result in a denial-of-service for GPFS.
A security vulnerability has been identified in GPFS, which affects 'setuid'
commands that may be run by non-root users.
When certain arguments are passed to those commands, their execution may
result in either the GPFS daemon crashing or the command itself crashing.
The abnormal termination of the daemon is considered a denial-of-service
to users of GPFS, since file system operations are suspended until the
daemon restarts and rejoins the cluster.
The abnormal termination of the program has not yet shown to cause any
other effects besides the program terminating.
