Descriptions

In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, a hostile MySQL server can cause the client to disclose the content of its heap containing data from other SQL requests and possible other data belonging to different users of the same server.

A flaw was found in the PHP MySQL client library. This vulnerability allows a hostile MySQL server to disclose the content of the client's heap, potentially exposing data from other SQL requests and other users of the same server via malicious server interactions.

It was discovered that PHP incorrectly handled certain inputs when processed with convert.quoted-printable decode filters. An attacker could possibly use this issue to expose sensitive information or cause a crash. It was discovered that PHP incorrectly handled certain HTTP requests. An attacker could possibly use this issue to performing arbitrary HTTP requests originating from the server, thus potentially gaining access to resources not normally available to the external user.
