CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2017-7542 – kernel: Integer overflow in ip6_find_1stfragopt() causes infinite loop
https://notcve.org/view.php?id=CVE-2017-7542
The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel through 4.12.3 allows local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket. La función ip6_find_1stfragopt en el archivo net/ipv6/output_core.c en el kernel de Linux hasta la versión 4.12.3, permite a los usuarios locales causar una denegación de servicio (desbordamiento de enteros y bucle infinito) mediante la explotación de la capacidad de abrir un socket sin procesar. An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6399f1fae4ec29fab5ec76070435555e256ca3a6 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.securityfocus.com/bid/99953 https://access.redhat.com/errata/RHSA-2017:2918 https://access.redhat.com/errata/RHSA-2017:2930 https://access.redhat.com/errata/RHSA-2017:2931 https://access.redhat.com/errata/RHSA-2018:0169 https://github.com/torvalds/linux/commit/6399f • CWE-190: Integer Overflow or Wraparound CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel before 4.12 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table. La función acpi_ns_terminate() en el archivo drivers/acpi/acpica/nsutils.c en el kernel de Linux anterior a versión 4.12, no limpia la caché operand y causa un volcado de pila del kernel, que permite a los usuarios locales obtener información confidencial de la memoria del kernel y omitir el mecanismo de protección KASLR (en el kernel hasta versión 4.9) por medio de una tabla ACPI creada. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3b2d69114fefa474fca542e51119036dceb4aa6f https://github.com/acpica/acpica/commit/a23325b2e583556eae88ed3f764e457786bf4df6 https://github.com/torvalds/linux/commit/3b2d69114fefa474fca542e51119036dceb4aa6f https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3754-1 • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2017-11176
The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact. La función mq_notify en el kernel de Linux hasta versión 4.11.9 no se ajusta el puntero sock a NULL al ingresar a la lógica de reintento. Durante un cierre de espacio de usuario de un socket Netlink, permite que los atacantes causen una denegación de servicio (uso de memoria previamente liberada) o posiblemente tengan otro impacto no especificado. A use-after-free flaw was found in the Netlink functionality of the Linux kernel networking subsystem. • https://www.exploit-db.com/exploits/45553 https://github.com/c3r34lk1ll3r/CVE-2017-11176 https://github.com/Sama-Ayman-Mokhtar/CVE-2017-11176 https://github.com/HckEX/CVE-2017-11176 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f991af3daabaecff34684fd51fac80319d1baad1 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.securityfocus.com/bid/99919 https://access.redhat.com/errata/RHSA-2017:2918 https: • CWE-416: Use After Free •
