CVSS: 6.5EPSS: 0%CPEs: 26EXPL: 0CVE-2016-4020 – Qemu: i386: leakage of stack memory to guest in kvmvapic.c
https://notcve.org/view.php?id=CVE-2016-4020
The patch_instruction function in hw/i386/kvmvapic.c in QEMU does not initialize the imm32 variable, which allows local guest OS administrators to obtain sensitive information from host stack memory by accessing the Task Priority Register (TPR). La función patch_instruction en hw/i386/kvmvapic.c en QEMU no inicializa la variable imm32, lo que permite a administradores locales del SO invitado obtener información sensible de la memoria de pila del anfitrión accediendo al Task Priority Register (TPR). An information-exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR) optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user inside a guest could use this issue to read portions of the host memory. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=691a02e2ce0c413236a78dee6f2651c937b09fb0 http://www.securityfocus.com/bid/86067 http://www.ubuntu.com/usn/USN-2974-1 https://access.redhat.com/errata/RHSA-2017:1856 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://bugzilla.redhat.com/show_bug.cgi?id=1313686 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The ne2000_receive function in the NE2000 NIC emulation support (hw/net/ne2000.c) in QEMU before 2.5.1 allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via crafted values for the PSTART and PSTOP registers, involving ring buffer control. La función ne2000_receive en el soporte de emulación NE2000 NIC (hw/net/ne2000.c) en QEMU en versiones anteriores a 2.5.1 permite a administradores locales del SO invitado provocar una denegación de servicio (bucle infinito y caída del proceso QEMU) a través de valores manipulados para los registros PSTART y PSTOP, involucrando control de anillo de buffer. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=415ab35a441eca767d033a2702223e785b9d5190 http://lists.nongnu.org/archive/html/qemu-stable/2016-03/msg00064.html http://www.openwall.com/lists/oss-security/2016/03/02/8 http://www.securityfocus.com/bid/84028 http://www.ubuntu.com/usn/USN-2974-1 https://bugzilla.redhat.com/show_bug.cgi?id=1303106 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-02/msg06126.h • CWE-20: Improper Input Validation •
