>> Sun Solaris NFSv4 Client Kernel Module Denial of Service Vulnerability
|
A vulnerability has been identified in Sun Solaris, which could be exploited by local attackers to cause a denial of service. This issue is caused by an unspecified error in the NFSv4 client kernel module, which may allow a local unprivileged user who cooperates with a remote privileged user on an NFSv4 server to be able to cause all NFSv4 mounts on client systems which have an NFSv4 mount of the above NFSv4 server to become unresponsive, creating a denial of service condition.
