USN-6895-4: Linux kernel vulnerabilities

Read Time:3 Minute, 14 Second

It was discovered that the ATA over Ethernet (AoE) driver in the Linux
kernel contained a race condition, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2023-6270)

It was discovered that the HugeTLB file system component of the Linux
Kernel contained a NULL pointer dereference vulnerability. A privileged
attacker could possibly use this to to cause a denial of service.
(CVE-2024-0841)

It was discovered that the Open vSwitch implementation in the Linux kernel
could overflow its stack during recursive action operations under certain
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-1151)

Gui-Dong Han discovered that the software RAID driver in the Linux kernel
contained a race condition, leading to an integer overflow vulnerability. A
privileged attacker could possibly use this to cause a denial of service
(system crash). (CVE-2024-23307)

Bai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in
the Linux kernel contained a race condition, leading to an integer overflow
vulnerability. An attacker could possibly use this to cause a denial of
service (system crash). (CVE-2024-24861)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

SnakeKeylogger Attack

Read Time:1 Minute, 4 Second

What is the Attack?Threat actors are continuously preying on end users to unknowingly install a trojan stealer known as SnakeKeylogger or KrakenKeylogger. This trojan was developed using .NET and targets Windows users. Its arsenal includes keystroke logging, harvesting credentials, and capturing screenshots. Based on the FortiGuard telemetry, there were hundreds of 0-day detection hits. Moreover, the sites that the trojan connects to were queried several times which suggests infection.What is the recommended Mitigation?FortiGuard Labs recommends a multi-layered approach to security. Here are some reminders:Keep your security services up to date with latest databases and engines.Enable Antivirus and Sandbox on security profiles in network policies.Use EDR for protecting end users from any pre and post exploitation.Be cautious when opening emails, clicking links, and downloading attachments.What FortiGuard Coverage is available?FortiGuard 0-day protection via Sandbox and EDR detects the malicious behavior.FortiGuard Antivirus protection detects the trojan as MSIL/Agent.RAT!tr.FortiGuard IOC Service blocks access to the payload site as a Spam/Malicious site.The FortiGuard Incident Response team can be engaged to help with any suspected compromise.To learn more about the SnakeKeylogger trojan, read the Encyclopedia Report posted by FortiGuard Labs at:https://www.fortiguard.com/encyclopedia/virus/10187160

USN-6943-1: Tomcat vulnerabilities

Read Time:1 Minute, 12 Second

It was discovered that Tomcat incorrectly handled certain uncommon
PersistenceManager with FileStore configurations. A remote attacker could
possibly use this issue to execute arbitrary code. This issue only affected
tomcat8 for Ubuntu 18.04 LTS (CVE-2020-9484)

It was discovered that Tomcat incorrectly handled certain HTTP/2 connection
requests. A remote attacker could use this issue to obtain wrong responses
possibly containing sensitive information. This issue only affected tomcat8
for Ubuntu 18.04 LTS (CVE-2021-25122)

Thomas Wozenilek discovered that Tomcat incorectly handlded certain TLS
packets. A remote attacker could possibly use this issue to cause a denial
of service. This issue only affected tomcat8 for Ubuntu 18.04 LTS
(CVE-2021-41079)

Trung Pham discovered that a race condition existed in Tomcat when handling
session files with FileStore. A remote attacker could possibly use this
issue to execute arbitrary code. This issue affected tomcat8 for Ubuntu
16.04 LTS and Ubuntu 18.04 LTS, and tomcat9 for Ubuntu 18.04 LTS and Ubuntu
20.04 LTS (CVE-2022-23181)

It was discovered that Tomcat’s documentation incorrectly stated that
EncryptInterceptor provided availability protection when running over an
untrusted network. A remote attacker could possibly use this issue to cause
a denial of service even if EncryptInterceptor was being used. This issue
affected tomcat8 for Ubuntu 18.04 LTS, and tomcat9 for Ubuntu 18.04 LTS,
Ubuntu 20.04 LTS and Ubuntu 22.04 LTS (CVE-2022-29885)

USN-6909-1 fixed several vulnerabilities in Bind. This update provides
the corresponding update for Ubuntu 18.04 LTS.

Original advisory details:

Toshifumi Sakaguchi discovered that Bind incorrectly handled having a very
large number of RRs existing at the same time. A remote attacker could
possibly use this issue to cause Bind to consume resources, leading to a
denial of service. (CVE-2024-1737)

Read Time:1 Minute, 43 Second

黄思聪 discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel did not properly handle certain memory allocation failure
conditions, leading to a null pointer dereference vulnerability. A local
