Xen through 4.14.x allows guest OS administrators to obtain sensitive information (such as AES keys from outside the guest) via a side-channel attack on a power/energy monitoring interface, aka a "Platypus" attack. NOTE: there is only one logically independent fix: to change the access control for each such interface in Xen. Xen versiones hasta 4.14.x, permite a administradores de Sistemas Operativos invitados obtener información confidencial (tales como claves AES desde fuera del invitado) por medio de un ataque de canal lateral en una interfaz de monitoreo de power/energy, también se conoce como un ataque "Platypus". NOTA: solo existe una corrección lógicamente independiente: cambiar el control de acceso para cada interfaz de este tipo en Xen • http://www.openwall.com/lists/oss-security/2020/11/26/1 http://xenbits.xen.org/xsa/advisory-351.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5J66QUUHXH2RR4CNCKQRGVXVSOUFRPDA https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XV23EZIMNLJN4YXRRXLQV2ALW6ZEALXV https://platypusattack.com https://www.debian.org/security/2020/dsa-4804 https://www.zdnet.com/article/new-platypus-attack-can-steal-data-from-intel-cpus https:&# • CWE-862: Missing Authorization •

In exif_entry_get_value of exif-entry.c, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution if a third party app used this library to process remote image data with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-8.1 Android-9 Android-10 Android-11 Android-8.0Android ID: A-159625731 En la función exif_entry_get_value del archivo exif-entry.c, se presenta una posible escritura fuera de límites debido a un desbordamiento de enteros. Esto podría conllevar a una ejecución de código remota si una aplicación de terceros usa esta biblioteca procesa datos remotos de imágenes sin ser necesarios privilegios de ejecución adicionales. No es requerida una interacción del usuario para su explotación. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ELDZR6USD5PR34MRK2ZISLCYJ465FNKN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVBD5JRUQPN4LQHTAAJHA3MR5M7YTAC7 https://security.gentoo.org/glsa/202011-19 https://source.android.com/security/bulletin/2020-11-01 https://access.redhat.com/security/cve/CVE-2020-0452 https://bugzilla.redhat.com/show_bug.cgi?id=1902004 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
