USN-4279-1 fixed vulnerabilities in PHP. The updated packages caused a regression. This update fixes the problem.

We apologize for the inconvenience.

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
