  • 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.
