Multi-vulnerability solutions for Xerces-C++ in various Ubuntu versions highlighted with critical updates for security.
Several security issues were fixed in Xerces-C++.

Summary

Several security issues were fixed in Xerces-C++.

Software Description:

- xerces-c: Validating XML parser written in a portable subset of C++

Details:

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. (CVE-2018-1311)

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)
