critical Nessus Plugin ID 183151

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5455-1 advisory.

 Tim Boddy, Gustavo Grieco and others discovered that Expat, that is integrated in xmltok library, incorrectly handled certain files. An attacker could possibly use these issues to cause a denial of service, or possibly execute arbitrary code. These issues were only addressed in Ubuntu 16.04 ESM.
 (CVE-2012-1148, CVE-2015-1283, CVE-2016-0718, CVE-2016-4472, CVE-2018-20843, CVE-2019-15903, CVE-2021-46143, CVE-2022-22822, CVE-2022-22823, CVE-2022-22824, CVE-2022-22825, CVE-2022-22826, CVE-2022-22827)

 It was discovered that Expat, that is integrated in xmltok library, incorrectly handled encoding validation of certain files. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-25235)

 It was discovered that Expat, that is integrated in xmltok library, incorrectly handled namespace URIs of certain files. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-25236)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libxmltok1 and / or libxmltok1-dev packages.
