CVE-2016-2150 – spice: Host memory access from guest with invalid primary surface parameters
https://notcve.org/view.php?id=CVE-2016-2150
SPICE allows local guest OS users to read from or write to arbitrary host memory locations via crafted primary surface parameters, a similar issue to CVE-2015-5261. SPICE permite a usuarios invitados locales del sistema operativo leer de o escribir a localizaciones de memoria de acogidas arbitrarias a través de parámetros de superficie primaria manipulados, un problema similar a CVE-2015-5261. A memory access flaw was found in the way spice handled certain guests using crafted primary surface parameters. A user in a guest could use this flaw to read from and write to arbitrary memory locations on the host. • http://lists.opensuse.org/opensuse-updates/2016-07/msg00003.html http://lists.opensuse.org/opensuse-updates/2016-07/msg00004.html http://www.debian.org/security/2016/dsa-3596 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.ubuntu.com/usn/USN-3014-1 https://access.redhat.com/errata/RHSA-2016:1204 https://access.redhat.com/errata/RHSA-2016:1205 https://bugzilla.redhat.com/show_bug.cgi?id=1313496 https://security.gentoo.org/glsa/201606& • CWE-284: Improper Access Control •
CVE-2016-0749 – spice: heap-based memory corruption within smartcard handling
https://notcve.org/view.php?id=CVE-2016-0749
The smartcard interaction in SPICE allows remote attackers to cause a denial of service (QEMU-KVM process crash) or possibly execute arbitrary code via vectors related to connecting to a guest VM, which triggers a heap-based buffer overflow. La interacción smartcard en SPICE permite a atacantes remotos provocar un denegación de servicio (caída del proceso QEMU-KVM) o ejecutar, posiblemente, un código arbitrario a través de véctores relacionados con conectarse con un invitado VM, lo que ejecuta un desbordamiento de bufer basado en memoria dinámica. A memory allocation flaw, leading to a heap-based buffer overflow, was found in spice's smartcard interaction, which runs under the QEMU-KVM context on the host. A user connecting to a guest VM using spice could potentially use this flaw to crash the QEMU-KVM process or execute arbitrary code with the privileges of the host's QEMU-KVM process. • http://lists.opensuse.org/opensuse-updates/2016-07/msg00003.html http://lists.opensuse.org/opensuse-updates/2016-07/msg00004.html http://www.debian.org/security/2016/dsa-3596 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.ubuntu.com/usn/USN-3014-1 https://access.redhat.com/errata/RHSA-2016:1204 https://access.redhat.com/errata/RHSA-2016:1205 https://security.gentoo.org/glsa/201606-05 https://access.redhat.com/security/cve/CVE-2016 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
