It was discovered that ImageMagick incorrectly handled memory under
certain circumstances. If a user were tricked into opening a specially
crafted image, an attacker could possibly exploit this issue to cause a
denial of service or other unspecified impact.

LSN-0086-1: Kernel Live Patch Security Notice

June 1, 2022

Read Time:1 Minute, 35 Second

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.(CVE-2021-39713)

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.(CVE-2022-0492)

It was discovered that the network traffic control implementation in the
Linux kernel contained a use-after-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code.(CVE-2022-1055)

Bing-Jhong Billy Jheng discovered that the io_uring subsystem in the Linux
kernel contained in integer overflow. A local attacker could use this to
cause a denial of service (system crash) or execute arbitrary code.(CVE-2022-1116)

It was discovered that the Linux kernel did not properly restrict access to
the kernel debugger when booted in secure boot environments. A privileged
attacker could use this to bypass UEFI Secure Boot restrictions.(CVE-2022-21499)

Nick Gregory discovered that the Linux kernel incorrectly handled network
offload functionality. A local attacker could use this to cause a denial of
service or possibly execute arbitrary code.(CVE-2022-25636)

Kyle Zeng discovered that the Network Queuing and Scheduling subsystem of
the Linux kernel did not properly perform reference counting in some
situations, leading to a use-after-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or execute
arbitrary code.(CVE-2022-29581)

Jann Horn discovered that the Linux kernel did not properly enforce seccomp
restrictions in some situations. A local attacker could use this to bypass
intended seccomp sandbox restrictions.(CVE-2022-30594)

A Vulnerability in Microsoft Support Diagnostic Tool (MSDT) Could Allow for Arbitrary Code Execution

June 1, 2022

Read Time:28 Second

A vulnerability in Microsoft Support Diagnostic Tool (MSDT) could allow for arbitrary code execution. MSDT collects information from hosts running Microsoft Windows and Windows Server to send to Microsoft Support. Successful exploitation of this vulnerability could result in arbitrary code execution. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

USN-5457-1: WebKitGTK vulnerabilities

June 1, 2022

Read Time:16 Second

A large number of security issues were discovered in the WebKitGTK Web and
JavaScript engines. If a user were tricked into viewing a malicious
website, a remote attacker could exploit a variety of issues related to web
browser security, including cross-site scripting attacks, denial of service
attacks, and arbitrary code execution.
