CVSS: 9.8EPSS: 8%CPEs: 15EXPL: 1CVE-2018-8787 – freerdp: Integer overflow leading to heap-based buffer overflow in gdi_Bitmap_Decompress() function
https://notcve.org/view.php?id=CVE-2018-8787
FreeRDP prior to version 2.0.0-rc4 contains an Integer Overflow that leads to a Heap-Based Buffer Overflow in function gdi_Bitmap_Decompress() 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 desbordamiento de enteros que conduce a un desbordamiento de búfer basado en memoria dinámica (heap) en la función gdi_Bitmap_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 before versions 2.0.0-rc4. An integer overflow that leads to a heap-based buffer overflow in the gdi_Bitmap_Decompress() function leads to 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/09b9d4f1994a674c4ec85b4947aa656eda1aed8a https://lists.debian.org/debian-lts-announce/2019/02/msg00015.html 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://access.redhat.com/security/cve/CVE-2018-8787 https://bugzilla.redhat.com/show_bug.cgi?id=1671361 • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 5.5EPSS: 0%CPEs: 15EXPL: 0CVE-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 •
