TITLE:
Globus Toolkit Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA21516

VERIFY ADVISORY:
http://secunia.com/advisories/21516/

CRITICAL:
Less critical

IMPACT:
Exposure of sensitive information, Privilege escalation

WHERE:
Local system

SOFTWARE:
Globus Toolkit 3.x
http://secunia.com/product/11499/
Globus Toolkit 4.x
http://secunia.com/product/11500/

DESCRIPTION:
Some vulnerabilities have been reported in the Globus Toolkit, which
potentially can be exploited by malicious, local users to disclose
sensitive information or perform certain actions with escalated
privileges.

1) A race condition exists in the grid-proxy-init tool between
opening the proxy credential file and verifying it's permissions
before writing into it. This may be exploited to gain knowledge of
sensitive information.

2) Various applications of the Globus Toolkit create temporary files
insecurely in the "/tmp" directory. This can be exploited via symlink
attacks to create or overwrite arbitrary files with the privileges of
the user running the applications.

SOLUTION:
Update to version 3.2.1 or 4.0.2.

PROVIDED AND/OR DISCOVERED BY:
1) Benjamin Bennett, Pittsburgh Supercomputing Center
2) Alex Lambert, NCSA
