The bdrv_open function in Qemu 1.0 does not properly handle the failure of the mkstemp function, when in snapshot node, which allows local users to overwrite or read arbitrary files via a symlink attack on an unspecified temporary file. La función bdrv_open en Qemu v1.0 no gestiona de forma adecuada el fallo en la función mkstemp en un nodo snapshot, lo que permite a usuario locales sobrescribir o leer ficheros a través de un ataque de enlace simbólico sobre un fichero temporal no especificado. • http://git.kernel.org/?p=virt/kvm/qemu-kvm.git%3Ba=commit%3Bh=eba25057b9a5e19d10ace2bc7716667a31297169 http://git.qemu.org/?p=qemu-stable-0.15.git%3Ba=log http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00024.html http://secunia.com/advisories/50132 http://secunia.com/advisories/50689 http://www.debian.org/security/2012/dsa-2545 http://www.securityfocus.com/bid/53725 http://www.ubuntu.com/usn/USN-1522-1 •

Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message. Desbordamiento de buffer en la función ccid_card_vscard_handle_message en hw/ccid-card-passthru.c en QEMU anterior a 0.15.2 y 1.x anterior a 1.0-rc4 permite a atacantes remotos causar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un mensaje VSC_ATR manipulado. • http://git.qemu.org/?p=qemu-stable-0.15.git%3Ba=log http://git.qemu.org/?p=qemu.git%3Ba=log%3Bh=refs/heads/stable-1.0 http://rhn.redhat.com/errata/RHSA-2011-1777.html http://rhn.redhat.com/errata/RHSA-2011-1801.html https://bugzilla.redhat.com/show_bug.cgi?id=751310 https://access.redhat.com/security/cve/CVE-2011-4111 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
