CVE-2023-37536

Un desbordamiento de enteros de xerces-c++ 3.2.3 en BigFix Platform permite a atacantes remotos provocar acceso fuera de límites a través de una solicitud HTTP.

An integer overflow exists in xerces-c++. This flaw allows an attacker using a specially crafted HTTP request payload to trigger an out-of-bounds read, resulting in a loss of confidentiality, integrity, and availability.

It was discovered that Xerces-C++ was not properly handling memory management operations when parsing XML data containing external DTDs, which could trigger a use-after-free error. If a user or automated system were tricked into processing a specially crafted XML document, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 22.04 LTS. It was discovered that Xerces-C++ was not properly performing bounds checks when processing XML Schema Definition files, which could lead to an out-of-bounds access via an HTTP request. If a user or automated system were tricked into processing a specially crafted XSD file, a remote attacker could possibly use this issue to cause a denial of service.
