參考資料	描述
CVE-2003-0187	Program uses large timeouts on unconfirmed connections resulting from inconsistency in linked lists implementations.
CVE-2003-0465	"strncpy" in Linux kernel acts different than libc on x86, leading to expected behavior difference - sort of a multiple interpretation error?
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.

漏洞對應備注

理由說明 : 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.
備註 : 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.

備注

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