NVD Description

Note: Versions mentioned in the description apply only to the upstream qt5-qttools-libs-designer package and not the qt5-qttools-libs-designer package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Qt 5.12.2 through 5.14.2, as used in unofficial builds of Mumble 1.3.0 and other products, mishandles OpenSSL's error queue, which can cause a denial of service to QSslSocket users. Because errors leak in unrelated TLS sessions, an unrelated session may be disconnected when any handshake fails. (Mumble 1.3.1 is not affected, regardless of the Qt version.)
