CVE-2023-45935

Name of the Vulnerable Software and Affected Versions Qt versions 6 through 6.6

Description A NULL pointer dereference was discovered via the function QXcbConnection::initializeAllAtoms(). This issue is disputed because it is not expected that an X application should continue to run when there is arbitrary anomalous behavior from the X server.

Recommendations For Qt versions 6 through 6.6, consider disabling the QXcbConnection::initializeAllAtoms() function as a temporary workaround until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
