TITLE:
Generic Software Wrappers Toolkit Multiple Race Condition
Vulnerabilities

SECUNIA ADVISORY ID:
SA26469

VERIFY ADVISORY:
http://secunia.com/advisories/26469/

CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
Local system

SOFTWARE:
Generic Software Wrappers Toolkit 1.x
http://secunia.com/product/15335/

DESCRIPTION:
Robert Watson has reported some vulnerabilities in Generic Software
Wrappers Toolkit, which can be exploited by malicious, local users to
bypass certain security restrictions.

The vulnerabilities are caused due to race conditions in the
filtering of multiple system calls wrappers when processing userspace
arguments. This can be exploited to bypass access control restrictions
and prevent the logging of certain actions.

NOTE: The vulnerabilities might lead to the execution of arbitrary
code with the privileges of the root user.

The vulnerabilities are reported in version 1.6.3. Other versions may
also be affected.

SOLUTION:
Do not rely on the security provided by Generic Software Wrappers
Toolkit.
