CVE-2008-0003
Description
From CVE.org
Stack-based buffer overflow in the PAMBasicAuthenticator::PAMCallback function in OpenPegasus CIM management server (tog-pegasus), when compiled to use PAM and without PEGASUS_USE_PAM_STANDALONE_PROC defined, might allow remote attackers to execute arbitrary code via unknown vectors, a different vulnerability than CVE-2007-5360.
Mitigation
The tog-pegasus package is not installed by default on Red Hat Enterprise Linux.
tog-pegasus supplied by Red Hat binds only to one port (as plain http is
disabled), port 5989. The default firewall installed by Red Hat Enterprise
Linux will block remote access to this port. In normal use it's unlikely you'd
want to have this port accessible outside of an intranet anyway, and it's likely
to be blocked by enterprise border firewalls.
However if tog-pegasus has been installed and unblocked through the fireware,
the Red Hat Security Response Team believes that it would still be hard to
remotely exploit this issue to execute arbitrary code due to the default SELinux
targeted policy on Enterprise Linux 4 and 5, and the SELinux memory protections
enabled by default on Enterprise Linux 5.
Understanding the Weakness (CWE)
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
Integrity,Confidentiality,Availability,Access Control
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands; Bypass Protection Mechanism
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy.
Integrity,Confidentiality,Availability,Access Control,Other
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands; Bypass Protection Mechanism; Other
When the consequence is arbitrary code execution, this can often be used to subvert any other security service.
