NVD Description

Note: Versions mentioned in the description apply only to the upstream php7-sockets package and not the php7-sockets package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

In PHP versions 8.0.* before 8.0.29, 8.1.* before 8.1.20, 8.2.* before 8.2.7 when using SOAP HTTP Digest Authentication, random value generator was not checked for failure, and was using narrower range of values than it should have. In case of random generator failure, it could lead to a disclosure of 31 bits of uninitialized memory from the client to the server, and it also made easier to a malicious server to guess the client's nonce.
