An issue was discovered in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.17.3. A denial of service (memory corruption and BUG) can occur for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork. Se ha descubierto un problema en fs/xfs/libxfs/xfs_inode_buf.c en el kernel de Linux hasta la versión 4.17.3. Puede ocurrir una denegación de servicio (corrupción de memoria y BUG) para una imagen xfs corrupta después de encontrarse con un inode con formato extendido, pero tiene más extensiones que cabrían en el fork inode. An issue was discovered in the XFS filesystem in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel. • https://access.redhat.com/errata/RHSA-2019:1350 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://bugzilla.kernel.org/show_bug.cgi?id=199915 https://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git/commit/?h=for-next&id=23fcb3340d033d9f081e21e6c12c2db7eaa541d3 https://github.com/torvalds/linux/commit/23fcb3340d033d9f081e21e6c12c2db7eaa541d3 https://access.redhat.com/security/cve/CVE-2018-13095 https://bugzilla.redhat.com/show_bug.cgi?id=1597775 • CWE-476: NULL Pointer Dereference CWE-787: Out-of-bounds Write •

An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls. • https://bugzilla.kernel.org/show_bug.cgi?id=200189 https://github.com/lcytxw/bug_repro/tree/master/bug_200189 https://github.com/torvalds/linux/commit/78c9c4dfbf8c04883941445a195276bb4bb92c76 https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html https://usn.ubuntu.com/3847-1 https://usn.ubuntu.com/3847-2 https://usn.ubuntu.com/3847- • CWE-190: Integer Overflow or Wraparound •

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 •
