Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5006-1 advisory.

 It was discovered that PHP incorrectly handled certain PHAR files. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service, or possibly obtain sensitive information. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-7068)

 It was discovered that PHP incorrectly handled parsing URLs with passwords. A remote attacker could possibly use this issue to cause PHP to mis-parse the URL and produce wrong data. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 20.10. (CVE-2020-7071)

 It was discovered that PHP incorrectly handled certain malformed XML data when being parsed by the SOAP extension. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 20.10. (CVE-2021-21702)

 It was discovered that PHP incorrectly handled the pdo_firebase module. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2021-21704)

 It was discovered that PHP incorrectly handled the FILTER_VALIDATE_URL check. A remote attacker could possibly use this issue to perform a server- side request forgery attack. (CVE-2021-21705)

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.
