Debian: DSA-4935-1 Moderate: PHP 7.3 SSRF Bypass and Code Execution

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:
