The QSslSocket::sslErrors function in Qt before 4.6.5, 4.7.x before 4.7.6, 4.8.x before 4.8.5, when using certain versions of openSSL, uses an "incompatible structure layout" that can read memory from the wrong location, which causes Qt to report an incorrect error when certificate validation fails and might cause users to make unsafe security decisions to accept a certificate. La función QSslSocket::sslErrors en Qt anterior a v4.6.5, v4.7.x anterior a v4.7.6, v4.8.x anterior a v4.8.5, cuando se usan ciertas versiones de openSSL, usa un diseño de estructura incompatible que puede leer memoria desde una dirección erronea, lo que produce que Qt reporte un error incorrecto cuando el certificado de validación falle y puede causar a los usuarios que hagan decisiones de seguridad inseguras para aceptar certificados. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=697582 http://lists.opensuse.org/opensuse-updates/2013-01/msg00086.html http://lists.opensuse.org/opensuse-updates/2013-01/msg00089.html http://lists.opensuse.org/opensuse-updates/2013-02/msg00014.html http://lists.qt-project.org/pipermail/announce/2013-January/000020.html http://qt.gitorious.org/qt/qt/commit/3b14dc93cf0ef06f1424d7d6319a1af4505faa53%20%284.7%29 http://qt.gitorious.org/qt/qt/commit/691e78e5061d4cbc0de212d23b06c5dffddf2098%20%284.8%29 http • CWE-310: Cryptographic Issues •

The XMLHttpRequest object in Qt before 4.8.4 enables http redirection to the file scheme, which allows man-in-the-middle attackers to force the read of arbitrary local files and possibly obtain sensitive information via a file: URL to a QML application.

https://notcve.org/view.php?id=CVE-2013-0254
The QSharedMemory class in Qt 5.0.0, 4.8.x before 4.8.5, 4.7.x before 4.7.6, and other versions including 4.4.0 uses weak permissions (world-readable and world-writable) for shared memory segments, which allows local users to read sensitive information or modify critical program data, as demonstrated by reading a pixmap being sent to an X server. La clase QSharedMemory en Qt v5.0.0, v4.8.x anterior a v4.8.5, v4.7.x anterior a v4.7.6, y otras versiones incluida la v4.4.0 utiliza permisos débiles (escritura y lectura para todos los usuarios) para segmentos de memoria compartida, lo que permite a usuarios locales leer informacion sensible o modificar datos críticos del programa, como se demostró mediante la lectura de un pixmap enviado al servidor X. • http://lists.opensuse.org/opensuse-updates/2013-03/msg00014.html http://lists.opensuse.org/opensuse-updates/2013-03/msg00015.html http://lists.opensuse.org/opensuse-updates/2013-03/msg00019.html http://lists.qt-project.org/pipermail/announce/2013-February/000023.html http://rhn.redhat.com/errata/RHSA-2013-0669.html https://bugzilla.redhat.com/show_bug.cgi?id=907425 https://access.redhat.com/security/cve/CVE-2013-0254 • CWE-264: Permissions, Privileges, and Access Controls •
