Debian DSA-4935-1 : php7.3 - security update

medium Nessus Plugin ID 151423

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-4935 advisory.

 Multiple security issues were found in PHP, a widely-used open source general purpose scripting language which could result an SSRF bypass of the FILTER_VALIDATE_URL check and denial of service or potentially the execution of arbitrary code in the Firebird PDO. For the stable distribution (buster), these problems have been fixed in version 7.3.29-1~deb10u1. We recommend that you upgrade your php7.3 packages. For the detailed security status of php7.3 please refer to its security tracker page at: https://security- tracker.debian.org/tracker/php7.3

Tenable has extracted the preceding description block directly from the Debian 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

Upgrade the php7.3 packages.

For the stable distribution (buster), these problems have been fixed in version 7.3.29-1~deb10u1.
