CVE-2018-10322 – kernel: Invalid pointer dereference in xfs_ilock_attr_map_shared() when mounting crafted xfs image allowing denial of service
https://notcve.org/view.php?id=CVE-2018-10322
The xfs_dinode_verify function in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_ilock_attr_map_shared invalid pointer dereference) via a crafted xfs image. La función xfs_dinode_verify en fs/xfs/libxfs/xfs_inode_buf.c en el kernel de Linux, hasta la versión 4.16.3, permite que usuarios locales provoquen una denegación de servicio (desreferencia de puntero inválido en xfs_ilock_attr_map_shared) mediante una imagen xfs manipulada. The xfs_dinode_verify function in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel can cause a NULL pointer dereference in xfs_ilock_attr_map_shared function. An attacker could trick a legitimate user or a privileged attacker could exploit this by mounting a crafted xfs filesystem image to cause a kernel panic and thus a denial of service. • http://www.securityfocus.com/bid/103960 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://bugzilla.kernel.org/show_bug.cgi?id=199377 https://usn.ubuntu.com/4578-1 https://usn.ubuntu.com/4579-1 https://www.spinics.net/lists/linux-xfs/msg17215.html https://access.redhat.com/security/cve/CVE-2018-10322 https://bugzilla.redhat.com/show_bug.cgi?id=1571623 • CWE-476: NULL Pointer Dereference •
CVE-2018-1106 – PackageKit: authentication bypass allows to install signed packages without administrator privileges
https://notcve.org/view.php?id=CVE-2018-1106
An authentication bypass flaw has been found in PackageKit before 1.1.10 that allows users without administrator privileges to install signed packages. A local attacker can use this vulnerability to install vulnerable packages to further compromise a system. Se ha encontrado un fallo de omisión de autenticación en PackageKit, en versiones anteriores a la 1.1.10, que permite que usuarios con privilegios de administrador instalen paquetes firmados. Un atacante local puede emplear esta vulnerabilidad para instalar paquetes vulnerables para comprometer aún más un sistema.

CVE-2018-8781 – kernel: Integer overflow in drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() can allow attackers to execute code in kernel space
https://notcve.org/view.php?id=CVE-2018-8781
The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c at the Linux kernel version 3.4 and up to and including 4.15 has an integer-overflow vulnerability allowing local users with access to the udldrmfb driver to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space. La función udl_fb_mmap en drivers/gpu/drm/udl/udl_fb.c en el kernel de Linux en su versión 3.4 y hasta e incluyendo la versión 4.15 tiene una vulnerabilidad de desbordamiento de enteros que permite que usuarios locales con acceso al controlador udldrmfb obtengan permisos totales de lectura y escritura en páginas físicas del kernel, lo que resulta en la ejecución de código en el espacio del kernel. A an integer overflow vulnerability was discovered in the Linux kernel, from version 3.4 through 4.15, in the drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An attacker with access to the udldrmfb driver could exploit this to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space. • https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://patchwork.freedesktop.org/patch/211845 https://research.checkpoint.com/mmap-vulnerabilities-linux-kernel https://usn.ubuntu.com/3654-1 https://usn.ubuntu.com/3654-2 https://usn.ubuntu.com/3656-1 https://usn.ubuntu.com/3674-1 https://usn.ubuntu.com • CWE-190: Integer Overflow or Wraparound •
CVE-2017-17833 – openslp: Heap memory corruption in slpd/slpd_process.c allows denial of service or potentially code execution
https://notcve.org/view.php?id=CVE-2017-17833
OpenSLP releases in the 1.0.2 and 1.1.0 code streams have a heap-related memory corruption issue which may manifest itself as a denial-of-service or a remote code-execution vulnerability. Las versiones de OpenSLP en las secuencias de código 1.0.2 y 1.1.0 tienen un problema de corrupción de memoria relacionada con la memoria dinámica (heap), que puede manifestarse como una vulnerabilidad de denegación de servicio (DoS) o de ejecución remota de código. A use-after-free flaw in OpenSLP 1.x and 2.x baselines was discovered in the ProcessSrvRqst function. A failure to update a local pointer may lead to heap corruption. A remote attacker may be able to leverage this flaw to gain remote code execution. • http://support.lenovo.com/us/en/solutions/LEN-18247 https://access.redhat.com/errata/RHSA-2018:2240 https://access.redhat.com/errata/RHSA-2018:2308 https://lists.debian.org/debian-lts-announce/2018/04/msg00029.html https://security.gentoo.org/glsa/202005-12 https://sourceforge.net/p/openslp/mercurial/ci/151f07745901cbdba6e00e4889561b4083250da1 https://usn.ubuntu.com/3708-1 https://access.redhat.com/security/cve/CVE-2017-17833 https://bugzilla.redhat.com/show_bug.cgi?id=1572166 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •
