CVE-2018-8786 – freerdp: Integer truncation leading to heap-based buffer overflow in update_read_bitmap_update() function
https://notcve.org/view.php?id=CVE-2018-8786
FreeRDP prior to version 2.0.0-rc4 contains an Integer Truncation that leads to a Heap-Based Buffer Overflow in function update_read_bitmap_update() and results in a memory corruption and probably even a remote code execution. FreeRDP en versiones anteriores a la 2.0.0-rc4 contiene un truncamiento de enteros que conduce a un desbordamiento de búfer basado en memoria dinámica (heap) en la función zgfx_decompress() y que resulta en una corrupción de memoria y, probablemente, incluso en la ejecución remota de código. A flaw was found in freerdp in versions prior to version 2.0.0-rc4. An integer truncation that leads to a heap-based buffer overflow in the update_read_bitmap_update() function results in a memory corruption. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://www.securityfocus.com/bid/106938 https://access.redhat.com/errata/RHSA-2019:0697 https://github.com/FreeRDP/FreeRDP/commit/445a5a42c500ceb80f8fa7f2c11f3682538033f3 https://lists.debian.org/debian-lts-announce/2019/02/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YVJKO2DR5EY4C4QZOP7SNNBEW2JW6FHX https://research.checkpoint.com/reverse-rdp-attack-code-execution-on-rdp-clients https://usn.ubuntu.com/3845-1 https://usn.ubuntu.com/3845-2 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-680: Integer Overflow to Buffer Overflow CWE-681: Incorrect Conversion between Numeric Types CWE-787: Out-of-bounds Write •

CVE-2018-14646 – kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service
https://notcve.org/view.php?id=CVE-2018-14646
The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service. El kernel de Linux en versiones anteriores a la 4.15-rc8 era vulnerable a un error de desreferencia de puntero NULL en la función __netlink_ns_capable() en el archivo net/netlink/af_netlink.c. Un atacante local podría explotarlo cuando un espacio de nombres de red con un netnsid se asigne para provocar un kernel de pánico y ataque de denegación de servicio (DoS). The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. • https://access.redhat.com/errata/RHSA-2018:3651 https://access.redhat.com/errata/RHSA-2018:3666 https://access.redhat.com/errata/RHSA-2018:3843 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14646 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f428fe4a04cc339166c8bbd489789760de3a0cee https://marc.info/?l=linux-netdev&m=151500466401174&w=2 https://access.redhat.com/security/cve/CVE-2018-14646 https://bugzilla.redhat.com/show_bug.cgi?id=1630124 • CWE-476: NULL Pointer Dereference •
