CVSS: 3.3EPSS: 0%CPEs: 4EXPL: 0CVE-2018-13053 – kernel: Integer overflow in the alarm_timer_nsleep function
https://notcve.org/view.php?id=CVE-2018-13053
The alarm_timer_nsleep function in kernel/time/alarmtimer.c in the Linux kernel through 4.17.3 has an integer overflow via a large relative timeout because ktime_add_safe is not used. La función alarm_timer_nsleep en kernel/time/alarmtimer.c en el kernel de Linux hasta la versión 4.17.3 tiene un desbordamiento de enteros a través de un tiempo de espera relativo grande porque no se utiliza ktime_add_safe. A flaw was found in the alarm_timer_nsleep() function in kernel/time/alarmtimer.c in the Linux kernel. The ktime_add_safe() function is not used and an integer overflow can happen causing an alarm not to fire or possibly a denial-of-service if using a large relative timeout. • http://www.securityfocus.com/bid/104671 https://access.redhat.com/errata/RHSA-2019:0831 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://bugzilla.kernel.org/show_bug.cgi?id=200303 https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=5f936e19cc0ef97dbe3a56e9498922ad5ba1edef https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https • CWE-190: Integer Overflow or Wraparound •
CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2018-12931 – kernel: stack-based out-of-bounds write in ntfs_attr_find in the ntfs.ko
https://notcve.org/view.php?id=CVE-2018-12931
ntfs_attr_find in the ntfs.ko filesystem driver in the Linux kernel 4.15.0 allows attackers to trigger a stack-based out-of-bounds write and cause a denial of service (kernel oops or panic) or possibly have unspecified other impact via a crafted ntfs filesystem. ntfs_attr_find en el controlador en el sistema de archivos ntfs.ko en el kernel de Linux 4.15.0 permite que los atacantes desencadenen una escritura fuera de límites basada en la pila de memoria y provoquen una denegación de servicio (OOPS o pánico del kernel) o, posiblemente, provoquen otro impacto no especificado mediante un sistema de archivos ntfs manipulado. A flaw was found in ntfs_attr_find in the ntfs.ko filesystem driver in the Linux kernel. This allows attackers to trigger a stack-based out-of-bounds write and cause a denial of service or possibly have unspecified other impact via a crafted ntfs filesystem image. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://www.securityfocus.com/bid/104588 https://access.redhat.com/errata/RHSA-2019:0641 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763403 https://marc.info/?l=linux-ntfs-dev&m=152413769810234&w=2 https://access.redhat.com/security/cve/CVE-2018-12931 https://bugzilla.redhat.com/show_bug.cgi?id=1597843 • CWE-787: Out-of-bounds Write •
