The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. • http://seclists.org/oss-sec/2017/q4/357 http://www.securityfocus.com/bid/102101 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2018:1130 https://access.redhat.com/errata/RHSA-2018:1170 https://access.redhat.com/errata/RHSA-2018:1319 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Memory leak in drivers/media/video/videobuf-core.c in the videobuf subsystem in the Linux kernel 2.6.x through 4.x allows local users to cause a denial of service (memory consumption) by leveraging /dev/video access for a series of mmap calls that require new allocations, a different vulnerability than CVE-2007-6761. NOTE: as of 2016-06-18, this affects only 11 drivers that have not been updated to use videobuf2 instead of videobuf. La pérdida de memoria en drivers/media/video/videobuf-core.c en el subsistema videobuf en el kernel de Linux 2.6.x hasta la versión 4.x permite a usuarios locales causar una denegación de servicio (consumo de memoria) aprovechando el acceso /dev/video para una serie de llamadas mmap que requieren nuevas asignaciones, una vulnerabilidad diferente a CVE-2007-6761. NOTA: a partir de 18-06-2016, esto afecta sólo a 11 controladores que no se han actualizado para utilizar videobuf2 en lugar de videobuf. • http://linuxtv.org/irc/v4l/index.php?date=2010-07-29 http://www.openwall.com/lists/oss-security/2015/02/08/4 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827340 https://bugzilla.kernel.org/show_bug.cgi?id=120571 https://bugzilla.redhat.com/show_bug.cgi?id=620629 • CWE-772: Missing Release of Resource after Effective Lifetime •

Linux Linux kernel version at least v4.8 onwards, probably well before contains a Insufficient input validation vulnerability in bnx2x network card driver that can result in DoS: Network card firmware assertion takes card off-line. This attack appear to be exploitable via An attacker on a must pass a very large, specially crafted packet to the bnx2x card. This can be done from an untrusted guest VM.. El kernel de Linux, al menos desde la versión v4.8, contiene una vulnerabilidad de validación de entradas insuficiente en el controlador de la tarjeta de red bnx2x que puede resultar en un DoS: la aserción del firmware de la tarjeta de red toma la tarjeta offline. Parece que el ataque puede ser explotado mediante un atacante que deba pasar un paquete muy grande, especialmente manipulado a la tarjeta bnx2x. • http://lists.openwall.net/netdev/2018/01/16/40 http://lists.openwall.net/netdev/2018/01/18/96 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://lists.debian.org/debian-lts-announce/2019/05/msg00002.html https://patchwork.ozlabs.org/patch/859410 https://usn.ubuntu.com/3617-1 https://usn.ubuntu.com/3617-2 https://usn.ubuntu.com/3617-3 https://usn. • CWE-20: Improper Input Validation •

A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely. Se ha descubierto una vulnerabilidad en los nombres de espacio de red que afecta al kernel de Linux en versiones anteriores a la 4.14.11. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=21b5944350052d2583e82dd59b19a9ba94a007f0 http://seclists.org/oss-sec/2018/q1/7 http://www.securityfocus.com/bid/102485 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1946 https://access.redhat.com/security/cve/CVE-2017-15129 https://bugzilla.redhat.com/show_bug.cgi& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic. El kernel de Linux en versiones 2.6.32 y posteriores se ha visto afectado por una denegación de servicio (DoS): al inundar el puerto de diagnóstico 0x80 puede ocurrir una excepción que conduce a una situación de pánico del kernel. Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) is vulnerable to a DoS issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in DoS. • http://www.openwall.com/lists/oss-security/2017/12/04/2 http://www.securityfocus.com/bid/102038 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/security/cve/cve-2017-1000407 https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 https://usn.ubuntu.com/3617-1 https&# • CWE-248: Uncaught Exception CWE-754: Improper Check for Unusual or Exceptional Conditions •
