CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2017-9074 – kernel: net: IPv6 fragmentation implementation of nexthdr field may be associated with an invalid option
https://notcve.org/view.php?id=CVE-2017-9074
The IPv6 fragmentation implementation in the Linux kernel through 4.11.1 does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. La implementación IPv6 Fragmentation en el kernel de Linux hasta la versión 4.11.1 no considera que el campo nexthdr puede estar asociado a una opción no válida, lo que permite a los usuarios locales causar una denegación de servicio (lectura fuera de límites y BUG) o posiblemente tener otro impacto no especificado por medio de un socket creado y enviar llamadas del sistema. The IPv6 fragmentation implementation in the Linux kernel does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. 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=2423496af35d94a87156b063ea5cedffc10a70a1 http://www.debian.org/security/2017/dsa-3886 http://www.securityfocus.com/bid/98577 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://access.redhat.com/errata/RHSA-2018:0169 https://github.com/torvalds/linux/commit/2423496af35d94a87156b063ea5cedffc10a70a1 https://help.ecostruxureit.c • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2017-7495
fs/ext4/inode.c in the Linux kernel before 4.6.2, when ext4 data=ordered mode is used, mishandles a needs-flushing-before-commit list, which allows local users to obtain sensitive information from other users' files in opportunistic circumstances by waiting for a hardware reset, creating a new file, making write system calls, and reading this file. En el archivo fs/ext4/inode.c en el kernel de Linux anterior a versión 4.6.2, cuando es usado el modo data=ordered de ext4, maneja inapropiadamente una lista de necesidades de descarga antes de confirmar, lo que permite a los usuarios locales obtener información confidencial de los archivos de otros usuarios en circunstancias oportunistas al esperar un reinicio del hardware, crear un archivo nuevo, hacer llamadas al sistema de escritura y leer este archivo. A vulnerability was found in the Linux kernel where filesystems mounted with data=ordered mode may allow an attacker to read stale data from recently allocated blocks in new files after a system 'reset' by abusing ext4 mechanics of delayed allocation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=06bd3c36a733ac27962fea7d6f47168841376824 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.6.2 http://www.openwall.com/lists/oss-security/2017/05/15/2 http://www.securityfocus.com/bid/98491 https://bugzilla.redhat.com/show_bug.cgi?id=1450261 https://github.com/torvalds/linux/commit/06bd3c36a733ac27962fea7d6f47168841376824 https://source.android.com/security/bulletin/2017-09-01 https://access.redhat.com/security • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-665: Improper Initialization •
