Ubuntu Security Notice 5460-1 - It was discovered that Vim was incorrectly processing Vim buffers. An attacker could possibly use this issue to perform illegal memory access and expose sensitive information. It was discovered that Vim was not properly performing bounds checks for column numbers when replacing tabs with spaces or spaces with tabs, which could cause a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

NVIDIA DCGM runs on machines with NVIDIA GPUs to gather telemetry and GPU health data. nv-hostengine is a daemon that by default listens on the loopback interface, but can also listen on the network for requests coming in on port 5555 (remote mgmt). A native client named DCGMI allows users to make requests to the daemon to support a variety of functions. Malformed packets can cause the daemon (running as root or user account) to crash or potentially result in code execution. Versions less than 2.3.5 are affected.

Ubuntu Security Notice 5459-1 - Aurélien Aptel discovered that cifs-utils invoked a shell when requesting a password. In certain environments, a local attacker could possibly use this issue to escalate privileges. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. It was discovered that cifs-utils incorrectly used host credentials when mounting a krb5 CIFS file system from within a container. An attacker inside a container could possibly use this issue to obtain access to sensitive information. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.

IIPImage is distributed with a server that enables advanced, high-performance image manipulation for web-based streaming and viewing of high resolution images. The server component called iipsrv.fcgi processes requests from users and passes them to command handlers. Several crashes including an integer overflow were discovered by sending malformed requests to the server, allowing remote users without authentication to perform denial-of-service attacks or potentially crafted for remote code execution as the server's running user. Versions at least up to 1.1 may be affected.

It was discovered that a race condition existed in the network scheduling subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. A local attacker could use this to gain administrative privileges. Various other issues were also addressed.

Zyxel USG FLEX version 5.21 suffers from a command injection vulnerability.

Buffer Over-read in GitHub repository bfabiszewski/libmobi prior to 0.11.

net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free.

Ubuntu Security Notice 5458-1 - It was discovered that Vim was incorrectly handling virtual column position operations, which could result in an out-of-bounds read. An attacker could possibly use this issue to expose sensitive information. It was discovered that Vim was not properly performing bounds checks when updating windows present on a screen, which could result in a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

libdwarf 0.4.0 has a heap-based buffer over-read in _dwarf_check_string_valid in dwarf_util.c.
