CVSS: 4.4EPSS: 0%CPEs: 22EXPL: 0CVE-2014-3640 – qemu: slirp: NULL pointer deref in sosendto()
https://notcve.org/view.php?id=CVE-2014-3640
The sosendto function in slirp/udp.c in QEMU before 2.1.2 allows local users to cause a denial of service (NULL pointer dereference) by sending a udp packet with a value of 0 in the source port and address, which triggers access of an uninitialized socket. La función sosendto en slirp/udp.c en QEMU anterior a 2.1.2 permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo) mediante el envió de un paquete udp con un valor de 0 en el pueto y dirección de la fuente, lo que provoca el acceso a un socket no inicializado. A NULL pointer dereference flaw was found in the way QEMU handled UDP packets with a source port and address of 0 when QEMU's user networking was in use. A local guest user could use this flaw to crash the guest. • http://lists.nongnu.org/archive/html/qemu-devel/2014-09/msg03543.html http://lists.nongnu.org/archive/html/qemu-devel/2014-09/msg04598.html http://lists.nongnu.org/archive/html/qemu-devel/2014-09/msg04707.html http://rhn.redhat.com/errata/RHSA-2015-0349.html http://rhn.redhat.com/errata/RHSA-2015-0624.html http://www.debian.org/security/2014/dsa-3044 http://www.debian.org/security/2014/dsa-3045 http://www.ubuntu.com/usn/USN-2409-1 https://bugzilla.redhat. • CWE-476: NULL Pointer Dereference •
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 •
