§ Q & A

Microsoft is taking it easy on us this month. There are
51 CVEs resolved in the June Patch Tuesday update.
We have new releases of Chrome, Edge and Firefox
this Patch Tuesday so update all browsers. While
Adobe did update 167 CVEs across 10 products, they
were all listed as Priority 3 and Adobe Reader was not
in the lineup. Priorities this month are going to be the
browsers and the Windows OS.
For more details check out this month's Patch Tuesday
blog.

§ CVE-2023-50868 NSEC3 Closest Encloser Proof can Exhaust CPU
§ CVSS 3.1 Scores: 7.5 / 6.5
§ Severity: Important
§ Impact: Denial of Service
§ Affected Systems: Server 2012/2012 R2, Server 2016, Server 2019, and Server 2022
§ Per Mitre – The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276
guidance is skipped) allows remote attackers to cause a denial of service (CPU consumption for SHA-
1 computations) via DNSSEC responses in a random subdomain attack, aka the "NSEC3" issue. The
RFC 5155 specification implies that an algorithm must perform thousands of iterations of a hash
function in certain situations.
Publicly Disclosed Vulnerability

CVE-2024-32002
§ CVSS 3: 9.0
§ Flaw in specific git (a revision control system)
versions allows a maliciously configured repository
to trigger code execution during a clone operation.
§ Repositories w/ submodules can be crafted to
exploit a bug in Git whereby it can be fooled into
writing files not into the submodule's worktree but
into a `.git/` directory.
§ A user cloning the code from such a repository
would trigger a hook without any ability to inspect
the code that would execute.
Mitigation
To avoid the problem: disable symlink support for git
with "git config --global core.symlinks false" but
doing so may affect normal git operations.
Updating past affected versions is recommended.
Also, never clone untrusted repositories.
New and Notable Linux Vulnerabilities: 1
Highlighted by TuxCare

CVE-2024-0646
§ CVSS 3: 7.8
§ It was discovered that the TLS subsystem
(Transport Layer Security) in the Linux kernel did
not properly handle spliced messages.
§ This can lead to an out-of-bounds write
vulnerability. A local attacker could use this to
cause a denial of service (system crash) or
possibly execute arbitrary code.
Background
First published in 1999, TLS is a widely adopted
security protocol designed to facilitate privacy and
data security for communications over the Internet.
A primary use case of TLS is encrypting the
communication between web applications and
servers, such as web browsers loading a website.
Mitigation
Updating the kernel is highly recommended.

CVE-2024-1086
§ CVSS 3: 7.8
§ Flaw in Netfilter subsystem of the Linux kernel
that enables local privilege escalation. Can lead
to a double-free vulnerability in the code,
triggering a user-controlled crash.
§ Double free is a memory management flaw that
occurs when a program releases the same
memory block twice using the free() or delete
function.
Impact
Affects Kernel versions 3.15 to 6.8-rc1, and distros
like RHEL, Debian, Ubuntu, and derivatives.
Mitigation
Upgrade your Linux kernel as soon as possible.
We covered this flaw in April, but it’s freshly
significant again because it has been added to
CISA’s known exploited vulnerabilities (malicious
actors are looking for it in your systems).
