Unspecified vulnerability in globus-job-manager in Globus Toolkit 4.1.1 and earlier (globus_nexus-6.6 and earlier) allows remote attackers to cause a denial of service (resource exhaustion and system crash) via certain requests to temporary TCP ports for a GRAM2 job or its MPICH-G2 applications.

Globus Toolkit 3.2.x, 4.0.x, and 4.1.0 before 20060815 allow local users to obtain sensitive information (proxy certificates) and overwrite arbitrary files via a symlink attack on temporary files in the /tmp directory, as demonstrated by files created by (1) myproxy-admin-adduser, (2) grid-ca-sign, and (3) grid-security-config.

Race condition in the grid-proxy-init tool in Globus Toolkit 3.2.x, 4.0.x, and 4.1.0 before 20060815 allows local users to steal credential data by replacing the proxy credentials file in between file creation and the check for exclusive file access.
