Ubuntu 18.04 LTS : php7.2 vulnerability (USN-3702-2)

High Nessus Plugin ID 110940

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

USN-3702-1 fixed a vulnerability in PHP. PHP 7.2.7 did not actually include the fix for CVE-2018-12882. This update adds a backported patch to correct the issue.

We apologize for the inconvenience.

Original advisory details :

It was discovered that PHP incorrectly handled exif tags in certain images. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code.

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.

Solution

Update the affected packages.
