https://notcve.org/view.php?id=CVE-2014-7815
The set_pixel_format function in ui/vnc.c in QEMU allows remote attackers to cause a denial of service (crash) via a small bytes_per_pixel value. La función set_pixel_format en ui/vnc.c en QEMU permite a atacantes remotos causar una denegación de servicio (caída) a través de valores pequeños de bytes_per_pixel. An uninitialized data structure use flaw was found in the way the set_pixel_format() function sanitized the value of bits_per_pixel. An attacker able to access a guest's VNC console could use this flaw to crash the guest. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=e6908bfe8e07f2b452e78e677da1b45b1c0f6829 http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00019.html http://rhn.redhat.com/errata/RHSA-2015-0349.html http://rhn.redhat.com/errata/RHSA-2015-0624.html http://secunia.com/advisories/61484 http://secunia.com/advisories/62143 http://secunia.com/advisories/62144 http://support.citrix.com/article/CTX200892 http://www.debian.org/security/2014/dsa-3066 http://www.debian.org/secu • CWE-20: Improper Input Validation •
CVSS: 2.9EPSS: 0%CPEs: 25EXPL: 0CVE-2014-3615 – Qemu: information leakage when guest sets high resolution
https://notcve.org/view.php?id=CVE-2014-3615
The VGA emulator in QEMU allows local guest users to read host memory by setting the display to a high resolution. El emulador VGA en QEMU permite a usuarios locales invitados leer la memoria del anfitrión mediante la configuración de la pantalla a una resolución alta. An information leak flaw was found in the way QEMU's VGA emulator accessed frame buffer memory for high resolution displays. A privileged guest user could use this flaw to leak memory contents of the host to the guest by setting the display to use a high resolution in the guest. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=ab9509cceabef28071e41bdfa073083859c949a7 http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=c1b886c45dc70f247300f549dce9833f3fa2def5 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00014.html http://rhn.redhat.com/errata/RHSA-2014-1669.html http://rhn.redhat.com/errata/RHSA-2014-1670.html http://rhn.redhat.com/errata/RHSA-2014-1941.html http://secunia.com/advisories/61829 http://support.citrix.com/article/CTX200892 http://www.de • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
