python-twisted: HTTP request smuggling when presented with two Content-Length headers

In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request.

MileSight DeviceHub - CWE-305 Missing Authentication for Critical Function

CVE

NVIDIA GPU software for Linux contains a vulnerability where it can expose sensitive information to an actor that is not explicitly authorized to have access to that information. A successful exploit of this vulnerability might lead to information disclosure.

CVE

NVIDIA GPU Driver for Windows and Linux contains a vulnerability where an improper check or improper handling of exception conditions might lead to denial of service.

CVE

NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability where a user can cause an untrusted pointer dereference by executing a driver API. A successful exploit of this vulnerability might lead to denial of service, information disclosure, and data tampering.

CVE

NVIDIA GPU driver for Windows and Linux contains a vulnerability where a user can cause an out-of-bounds write. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.

CVE

NVIDIA vGPU software for Linux contains a vulnerability where the software can dereference a NULL pointer. A successful exploit of this vulnerability might lead to denial of service and undefined behavior in the vGPU plugin.

CVE

NVIDIA vGPU software for Windows and Linux contains a vulnerability where unprivileged users could execute privileged operations on the host. A successful exploit of this vulnerability might lead to data tampering, escalation of privileges, and denial of service.

CVE

NVIDIA vGPU software for Linux contains a vulnerability in the Virtual GPU Manager, where the guest OS could execute privileged operations. A successful exploit of this vulnerability might lead to information disclosure, data tampering, escalation of privileges, and denial of service.

A feature in LXD (LP#1829071), affects the default configuration of Ubuntu Server which allows privileged users in the lxd group to escalate their privilege to root without requiring a sudo password.

PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification, aka a GPU.zip issue. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin.

accountsservice: use-after-free via a D-Bus message to the accounts-daemon process

In Ubuntu's accountsservice an unprivileged local attacker can trigger a use-after-free vulnerability in accountsservice by sending a D-Bus message to the accounts-daemon process.

CVE

NVIDIA vGPU software for Windows and Linux contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where a NULL-pointer dereference may lead to denial of service.

CVE

NVIDIA vGPU software for Windows and Linux contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where a malicious user in the guest VM can cause a NULL-pointer dereference, which may lead to denial of service.

kernel: overlayfs: In Ubuntu skip permission checking for trusted.overlayfs.* xattrs

On Ubuntu kernels carrying both c914c0e27eb0 and "UBUNTU: SAUCE: overlayfs: Skip permission checking for trusted.overlayfs.* xattrs", an unprivileged user may set privileged extended attributes on the mounted files, leading them to be set on the upper files without the appropriate security checks.

A vulnerability has been discovered in the Citrix Secure Access client for Ubuntu which, if exploited, could allow an attacker to remotely execute code if a victim user opens an attacker-crafted link and accepts further prompts.

Using the TIOCLINUX ioctl request, a malicious snap could inject contents into the input of the controlling terminal which could allow it to cause arbitrary commands to be executed outside of the snap sandbox after the snap exits. Graphical terminal emulators like xterm, gnome-terminal and others are not affected - this can only be exploited when snaps are run on a virtual console.

kernel: io_uring IORING_OP_SOCKET double free

The Linux kernel io_uring IORING_OP_SOCKET operation contained a double free in function __sys_socket_file() in file net/socket.c. This issue was introduced in da214a475f8bd1d3e9e7a19ddfeb4d1617551bab and fixed in 649c15c7691e9b13cbe9bf6c65c365350e056067.

kernel: posix cpu timer use-after-free may lead to local privilege escalation

It was discovered that when exec'ing from a non-leader thread, armed POSIX CPU timers would be left on a list but freed, leading to a use-after-free.
