An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system. Se encontró un problema de acceso fuera de límites en el kernel de Linux, todas las versiones hasta 5.3, en la manera en que el hipervisor KVM del kernel de Linux implementa la operación de escritura MMIO Coalesced. Opera en un objeto MMIO ring buffer "struct kvm_coalesced_mmio", en donde los índices de escritura "ring-)first" y "ring-)last" podrían ser suministrados por un proceso de espacio de usuario del host. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00037.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/09/20/1 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517&# • CWE-787: Out-of-bounds Write •

When the default servlet in Apache Tomcat versions 9.0.0.M1 to 9.0.11, 8.5.0 to 8.5.33 and 7.0.23 to 7.0.90 returned a redirect to a directory (e.g. redirecting to '/foo/' when the user requested '/foo') a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice. Cuando el servlet por defecto en Apache Tomcat en versiones de la 9.0.0.M1 a la 9.0.11, de la 8.5.0 a la 8.5.33 y de la 7.0.23 a la 7.0.90 devolvía una redirección a un directorio (por ejemplo, redirigiendo a "/foo/'' cuando el usuario solicitó '"/foo") se pudo usar una URL especialmente manipulada para hacer que la redirección se generara a cualquier URI de la elección del atacante.

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS before 1.4.4, when kqueue or epoll is used, allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third party information. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-3553. Vulnerabilidad de uso despues de liberacion en el interfaz de gestion de descriptores de fichero en la funcion cupsdDoSelect en scheduler/select.c en the scheduler en cupsd en CUPS v1.3.7, v1.3.9, v1.3.10, y v1.4.1, cuando se utiliza kqueue o epoll, permite a atacantes remotos producir una denegacion de servicio (caida de demonio o cuelgue) a traves de la desconexion del cliente durante el listado de un gran numero de trabajos de imporesion, relacionados con el inadecuado mantenimiento del numero de referencias.

A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. NOTE: this is related to an issue in the Linux kernel before 2.6.31, when the kernel routing cache is disabled, involving an uninitialized pointer and a panic. Cierto parche de Red Hat para net/ipv4/route.c en el kernel de Linux v2.6.18 en Red Hat Enterprise Linux (RHEL) v5 permite a atacantes remotos producir una denegación de servicio (punto muerto) a traves de paquetes manipulados que que fuerzan colisiones en la tabla de hash de enrutamiento IPv4, e inicia un enrutado de "emergencia" en el cual la cadena de hash es demasiado larga. NOTA: Esta vulnerabilidad esta relacionada con otra del cache de enrutamiento del kernel cuando el cache de enrutamiento del kernel esta desactivado, implicando un puntero no inicializado y panic. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=73e42897e8e5619eacb787d2ce69be12f47cfc21 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b6280b47a7a42970d098a3059f4ebe7e55e90d8d http://support.avaya.com/css/P8/documents/100073666 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.31 http://www.openwall.com/lists/oss-security/2010/01/20/1 http://www.openwall.com/lists/oss-security/2010/01/20/6 https://bugz • CWE-476: NULL Pointer Dereference CWE-667: Improper Locking •
