Summary
The Qt framework's Network module, specifically its QAuthenticator NTLM authentication handling, is affected. A malicious server or proxy can send a crafted NTLM challenge that causes an out-of-bounds memory read, potentially exposing sensitive heap memory contents or crashing applications that use QNetworkAccessManager or QTcpSocket with NTLM authentication.

Read the original description
Out-of-bounds read in the QAuthenticator NTLM authentication handling in the Qt Network module in Qt Group Qt allows remote attackers to obtain sensitive information (heap memory contents) or cause a denial of service (application crash) via a crafted NTLM challenge sent by a malicious server or proxy, when an application using QNetworkAccessManager or QTcpSocket authenticates with NTLM.
