CVE-2014-0144 – Qemu: block: missing input validation
https://notcve.org/view.php?id=CVE-2014-0144
QEMU before 2.0.0 block drivers for CLOOP, QCOW2 version 2 and various other image formats are vulnerable to potential memory corruptions, integer/buffer overflows or crash caused by missing input validations which could allow a remote user to execute arbitrary code on the host with the privileges of the QEMU process. Los controladores de bloque de QEMU versiones anteriores a 2.0.0 para CLOOP, QCOW2 versión 2 y varios otros formatos de imagen son vulnerables a posibles corrupciones de memoria, desbordamientos de enteros/buffer o bloqueos causados por falta de comprobaciones de entrada que podrían permitir a un usuario remoto ejecutar código arbitrario en el host con los privilegios del proceso QEMU • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=24342f2cae47d03911e346fe1e520b00dc2818e0 http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=2d51c32c4b511db8bb9e58208f1e2c25e4c06c85 http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=5dab2faddc8eaa1fb1abdbe2f502001fc13a1b21 http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=63fa06dc978f3669dbfd9443b33cde9e2a7f4b41 http://git.qemu.org/? • CWE-20: Improper Input Validation •
CVE-2013-6393 – libyaml: heap-based buffer overflow when parsing YAML tags
https://notcve.org/view.php?id=CVE-2013-6393
The yaml_parser_scan_tag_uri function in scanner.c in LibYAML before 0.1.5 performs an incorrect cast, which allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted tags in a YAML document, which triggers a heap-based buffer overflow. La función yaml_parser_scan_tag_uri en scanner.c en LibYAML anterior a 0.1.5 lleva a cabo un "cast" incorrecto, lo que permite a atacantes remotos causar una denegación de servicio (caída de la aplicación) y probablemente ejecutar código arbitrario a través de etiquetas manipuladas en YAML. • http://advisories.mageia.org/MGASA-2014-0040.html http://archives.neohapsis.com/archives/bugtraq/2014-04/0134.html http://archives.neohapsis.com/archives/bugtraq/2014-10/0103.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00064.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00065.html http://lists.opensuse.org/opensuse-updates/2015-02/msg00078.html http://lists.opensuse.org/opensuse-updates/2016-04/msg00050.html http://osvdb.org/102716 http://rhn.redhat.com • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
