CVE-2018-1311

Xerces-C is a validating XML parser written in a portable subset of C++. Xerces-C makes it easy to give your application the ability to read and write XML data. A shared library is provided for parsing, generating, manipulating, and validating XML documents. Xerces-C is faithful to the XML 1.0 recommendation and associated standards ( DOM 1.0, DOM 2.0. SAX 1.0, SAX 2.0, Namespaces).

Security Fix(es):

The Apache Xerces-C 3.0.0 to 3.2.3 XML parser contains a use-after-free error triggered during the scanning of external DTDs. This flaw has not been addressed in the maintained version of the library and has no current mitigation other than to disable DTD processing. This can be accomplished via the DOM using a standard parser feature, or via SAX using the XERCES_DISABLE_DTD environment variable.(CVE-2018-1311)

A use-after-free vulnerability was found in xerces-c in the way an XML document is processed via the SAX API. Applications that process XML documents with an external Document Type Definition (DTD) may be vulnerable to this flaw. A remote attacker could exploit this flaw by creating a specially crafted XML file that would crash the application or potentially lead to arbitrary code execution (CVE-2018-1311).

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.

USN-6579-1 fixed a vulnerability in Xerces-C++. This update provides the corresponding update for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 23.04 and Ubuntu 23.10.

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. (CVE-2023-37536)
