https://notcve.org/view.php?id=CVE-2017-5898
Integer overflow in the emulated_apdu_from_guest function in usb/dev-smartcard-reader.c in Quick Emulator (Qemu), when built with the CCID Card device emulator support, allows local users to cause a denial of service (application crash) via a large Application Protocol Data Units (APDU) unit. Desbordamiento de entero en la función emulated_apdu_from_guest en usb/dev-smartcard-reader.c en Quick Emulator (Qemu), cuando se construye con el soporte de emulador de dispositivo de CCID Card, permite a usuarios locales provocar una denegación de servicio (caída de aplicación) a través de una unidad Unidad de datos de protocolo (APDU) grande. An integer overflow flaw was found in Quick Emulator (QEMU) in the CCID Card device support. The flaw could occur while passing messages via command/response packets to and from the host. A privileged user inside a guest could use this flaw to crash the QEMU process. • http://git.qemu-project.org/?p=qemu.git%3Ba=commit%3Bh=c7dfbf322595ded4e70b626bf83158a9f3807c6a http://lists.opensuse.org/opensuse-security-announce/2017-02/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2017-02/msg00048.html http://www.openwall.com/lists/oss-security/2017/02/07/3 http://www.securityfocus.com/bid/96112 https://access.redhat.com/errata/RHSA-2017:1856 https://access.redhat.com/errata/RHSA-2017:2392 https://bugzilla.redhat.com/show_bug.cgi?id=1419699 htt • CWE-190: Integer Overflow or Wraparound •
