CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2018-13093 – kernel: NULL pointer dereference in lookup_slow function
https://notcve.org/view.php?id=CVE-2018-13093
An issue was discovered in fs/xfs/xfs_icache.c in the Linux kernel through 4.17.3. There is a NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occurs because of a lack of proper validation that cached inodes are free during allocation. Se ha descubierto un problema en fs/xfs/xfs_icache.c en el kernel de Linux hasta la versión 4.17.3. Existe una desreferencia de puntero NULL y pánico en lookup_slow() en un puntero NULL inode->i_ops cuando se navega por rutas en una imagen xfs corrupta. • https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://bugzilla.kernel.org/show_bug.cgi?id=199367 https://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git/commit/?h=for-next&id=afca6c5b2595fc44383919fba740c194b0b76aff https://github.com/torvalds/linux/commit/afca6c5b2595fc44383919fba740c194b0b76aff https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://usn.ubuntu.com/4094-1 https://usn.ubuntu.com/4118-1 https://access.re • CWE-476: NULL Pointer Dereference •

An issue was discovered in fs/f2fs/inode.c in the Linux kernel through 4.17.3. A denial of service (slab out-of-bounds read and BUG) can occur for a modified f2fs filesystem image in which FI_EXTRA_ATTR is set in an inode. Se ha descubierto un problema en fs/f2fs/inode.c en el kernel de Linux hasta la versión 4.17.3. Puede ocurrir una denegación de servicio (lectura fuera de límites de slab y BUG) para una imagen de sistema de archivos f2fs modificada en el que FI_EXTRA_ATTR está establecido en un inode. • http://lists.opensuse.org/opensuse-security-announce/2018-10/msg00033.html https://bugzilla.kernel.org/show_bug.cgi?id=200173 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=76d56d4ab4f2a9e4f085c7d77172194ddaccf7d2 https://usn.ubuntu.com/4094-1 https://usn.ubuntu.com/4118-1 • CWE-125: Out-of-bounds Read •

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 •
