CVE-2007-1320 – xen/qemu Cirrus LGD-54XX "bitblt" Heap Overflow
https://notcve.org/view.php?id=CVE-2007-1320
Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow. Múltiples desbordamientos de búfer en la región heap de la memoria en la función cirrus_invalidate_region en la extensión Cirrus VGA en QEMU versión 0.8.2, como es usado en Xen y posiblemente otros productos, podrían permitir a usuarios locales ejecutar código arbitrario por medio de vectores no especificados relacionados a "attempting to mark non-existent regions as dirty," también se conoce como el desbordamiento de la pila "bitblt". • http://lists.opensuse.org/opensuse-security-announce/2009-01/msg00004.html http://osvdb.org/35494 http://secunia.com/advisories/25073 http://secunia.com/advisories/25095 http://secunia.com/advisories/27047 http://secunia.com/advisories/27085 http://secunia.com/advisories/27103 http://secunia.com/advisories/27486 http://secunia.com/advisories/29129 http://secunia.com/advisories/30413 http://secunia.com/advisories/33568 http://taviso.decsystem.org/virtsec.pdf http://www.de • CWE-787: Out-of-bounds Write •
CVE-2007-0998 – HVM guest VNC server allows compromise of entire host OS by any VNC console user
https://notcve.org/view.php?id=CVE-2007-0998
The VNC server implementation in QEMU, as used by Xen and possibly other environments, allows local users of a guest operating system to read arbitrary files on the host operating system via unspecified vectors related to QEMU monitor mode, as demonstrated by mapping files to a CDROM device. NOTE: some of these details are obtained from third party information. La implementación del servidor VNC en QEMU, como es usada por Xen y posiblemente otros entornos, permite a usuarios locales de un sistema operativo invitado leer archivos arbitrarios en el sistema operativo host por medio de vectores no especificados relacionados con el modo de monitoreo de QEMU, como es demostrado al mapear archivos hacia un dispositivo CDROM. NOTA: algunos de estos detalles son obtenidos a partir de información de terceros. • http://fedoranews.org/cms/node/2802 http://fedoranews.org/cms/node/2803 http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00017.html http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://osvdb.org/34304 http://rhn.redhat.com/errata/RHSA-2007-0114.html http://secunia.com/advisories/24575 http://secunia.com/advisories/51413 http://www.securityfocus.com/bid/22967 • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2006-6235
https://notcve.org/view.php?id=CVE-2006-6235
A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 through 1.9.95 allows attackers to execute arbitrary code via crafted OpenPGP packets that cause GnuPG to dereference a function pointer from deallocated stack memory. Una vulnerabilidad de "escritura en pila" en GnuPG (gpg) 1.x anterior a la 1.4.6, 2.x anterior a la 2.0.2 y 1.9.0 hasta la 1.9.95 permite a atacantes ejecutar código de su elección mediante paquetes OpenPGP artesanales que provocan que GnuPG haga referencia a un puntero a función que está en memoria (en la pila) que ya ha sido liberada. • ftp://patches.sgi.com/support/free/security/advisories/20061201-01-P.asc http://lists.gnupg.org/pipermail/gnupg-announce/2006q4/000491.html http://lists.suse.com/archive/suse-security-announce/2006-Dec/0004.html http://secunia.com/advisories/23245 http://secunia.com/advisories/23250 http://secunia.com/advisories/23255 http://secunia.com/advisories/23259 http://secunia.com/advisories/23269 http://secunia.com/advisories/23284 http://secunia.com/advisories/23290 http://secunia. •
