Ubuntu Security Notice 6590-1 - 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.

2c7f1904a8605b02abe1cc4cb1f85e2e9495b578c47b07e5a54f32d06a2a6fcfDebian Linux Security Advisory 4814-1 - It was discovered that xerces-c, a validating XML parser library for C++, did not correctly scan DTDs. The use-after-free vulnerability resulting from this issue would allow a remote attacker to leverage a specially crafted XML file in order to crash the application or potentially execute arbitrary code. Please note that the patch fixing this issue comes at the expense of a newly introduced memory leak.

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. Issues addressed include a use-after-free vulnerability.

306a1b1da1150eaae8df68a1866547196a2e7421d357e341f63e146f72c33c7fAn attacker with standard / low access rights within the web GUI is able to gain access to the CLI (if it has been previously disabled by the configuration) and escalate his privileges. Depending on the CLI features it is possible to extract the whole configuration and manipulate settings or gain access to debug features of the device, e.g. via "debug", "upgrade", "upload" etc. commands in the CLI. Attackers can gain access to sensitive configuration data such as VoIP credentials or other information and manipulate any settings of the device. Versions affected include ADB P.RG AV4202N, DV2210, VV2220, and VV5522.
