CVE-2003-0187

Program uses large timeouts on unconfirmed connections resulting from inconsistency in linked lists implementations.

CVE-2003-0465

CVE-2005-3265

Buffer overflow in product stems the use of a third party library function that is expected to have internal protection against overflows, but doesn't.

Notities kwetsbaarheidsmapping

Rechtvaardiging : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Opmerking : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Notities

The behavior of an application that is not consistent with the expectations of the developer may lead to incorrect use of the software.
