CVSS: 4.4EPSS: 0%CPEs: 61EXPL: 0CVE-2013-0254 – qt: QSharedMemory class created shared memory segments with insecure permissions
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 •

https://notcve.org/view.php?id=CVE-2010-5076
QSslSocket in Qt before 4.7.0-rc1 recognizes a wildcard IP address in the subject's Common Name field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority. QSslSocket de Qt anteriores a 4.7.0-rc1 reconoce direcciones IP comodín en el campo "Common Name" del "subject" de un certificado X.509, lo que permite a atacantes "man-in-the-middle" suplantar servidores SSL arbitrarios a través de un certificado modificado suministrado por una autoridad de certificación legítima. • http://qt.gitorious.org/qt/qt/commit/5f6018564668d368f75e431c4cdac88d7421cff0 http://qt.gitorious.org/qt/qt/commit/846f1b44eea4bb34d080d055badb40a4a13d369e http://rhn.redhat.com/errata/RHSA-2012-0880.html http://secunia.com/advisories/41236 http://secunia.com/advisories/49604 http://secunia.com/advisories/49895 http://www.ubuntu.com/usn/USN-1504-1 http://www.westpoint.ltd.uk/advisories/wp-10-0001.txt https://bugreports.qt-project.org/browse/QTBUG-4455 https://access.redhat.com/security/c • CWE-20: Improper Input Validation •
