Niels Dossche and Tim Düsterhus discovered that PHP's implementation of
the SOAP HTTP Digest authentication did not check for failures, which
may result in a stack information leak. Furthermore, the code used an
insufficient number of random bytes.

For Debian 10 buster, this problem has been fixed in version
7.3.31-1~deb10u4.

We recommend that you upgrade your php7.3 packages.
