脆弱性タイトル
Libexpat: expat: improper restriction of xml entity expansion depth in libexpat
ソース: CVE Program / CVE List V5
脆弱性説明
A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage.
