The remote Ubuntu 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4279-2 advisory.
USN-4279-1 fixed vulnerabilities in PHP. The updated packages caused a regression. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that PHP incorrectly handled certain scripts.
An attacker could possibly use this issue to cause a denial of service.
This issue only affected Ubuntu 12.04 ESM, Ubuntu 14.04 ESM and Ubuntu 16.04 LTS.
(CVE-2015-9253)
It was discovered that PHP incorrectly handled certain inputs. An attacker
could possibly use this issue to expose sensitive information.
(CVE-2020-7059)
It was discovered that PHP incorrectly handled certain inputs.
An attacker could possibly use this issue to execute arbitrary code.
This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS
and Ubuntu 19.10. (CVE-2020-7060)
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
