CVSS: 5.6EPSS: 97%CPEs: 1467EXPL: 3CVE-2017-5753 – Multiple CPUs - 'Spectre' Information Disclosure
https://notcve.org/view.php?id=CVE-2017-5753
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Los sistemas con microprocesadores con ejecución especulativa y predicción de ramas podrían permitir la revelación no autorizada de información al atacante con acceso de usuario local mediante un análisis de un canal lateral. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. • https://www.exploit-db.com/exploits/43427 https://github.com/sachinthaBS/Spectre-Vulnerability-CVE-2017-5753- http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00016.html http://nvidia.custhe • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVSS: 10.0EPSS: 95%CPEs: 66EXPL: 0CVE-2017-18017 – kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c
https://notcve.org/view.php?id=CVE-2017-18017
The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. La función tcpmss_mangle_packet en net/netfilter/xt_TCPMSS.c en el kernel de Linux, en versiones anteriores a la 4.11 y en versiones 4.9.x anteriores a la 4.9.36, permite que atacantes remotos provoquen una denegación de servicio (uso de memoria previamente liberada y corrupción de memoria) o, posiblemente, otro tipo de impacto sin especificar aprovechando la presencia de xt_TCPMSS en una acción iptables. The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2638fd0f92d4397884fd991d8f4925cb3f081901 http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00047.html http://lists.opensuse.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •

The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.
