USN-6729-2: Apache HTTP Server vulnerabilities

Read Time:42 Second

USN-6729-1 fixed several vulnerabilities in Apache. This update provides
the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

Original advisory details:

Orange Tsai discovered that the Apache HTTP Server incorrectly handled
validating certain input. A remote attacker could possibly use this
issue to perform HTTP request splitting attacks. (CVE-2023-38709)

Keran Mu and Jianjun Chen discovered that the Apache HTTP Server
incorrectly handled validating certain input. A remote attacker could
possibly use this issue to perform HTTP request splitting attacks.
(CVE-2024-24795)

Bartek Nowotarski discovered that the Apache HTTP Server HTTP/2 module
incorrectly handled endless continuation frames. A remote attacker could
possibly use this issue to cause the server to consume resources, leading
to a denial of service. This issue was addressed only in Ubuntu 18.04 LTS.

USN-6726-3: Linux kernel (Xilinx ZynqMP) vulnerabilities

Read Time:1 Minute, 25 Second

Pratyush Yadav discovered that the Xen network backend implementation in
the Linux kernel did not properly handle zero length data request, leading
to a null pointer dereference vulnerability. An attacker in a guest VM
could possibly use this to cause a denial of service (host domain crash).
(CVE-2023-46838)

It was discovered that the IPv6 implementation of the Linux kernel did not
properly manage route cache memory usage. A remote attacker could use this
to cause a denial of service (memory exhaustion). (CVE-2023-52340)

It was discovered that the device mapper driver in the Linux kernel did not
properly validate target size during certain memory allocations. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-52429, CVE-2024-23851)

Dan Carpenter discovered that the netfilter subsystem in the Linux kernel
did not store data in properly sized memory locations. A local user could
use this to cause a denial of service (system crash). (CVE-2024-0607)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
– Architecture specifics;
– Cryptographic API;
– Android drivers;
– EDAC drivers;
– GPU drivers;
– Media drivers;
– MTD block device drivers;
– Network drivers;
– NVME drivers;
– TTY drivers;
– Userspace I/O drivers;
– F2FS file system;
– GFS2 file system;
– IPv6 Networking;
– AppArmor security module;
(CVE-2023-52464, CVE-2023-52448, CVE-2023-52457, CVE-2023-52443,
CVE-2023-52439, CVE-2023-52612, CVE-2024-26633, CVE-2024-26597,

Multiple Vulnerabilities in Google Chrome Could Allow for Remote Code Execution

Read Time:26 Second

Multiple vulnerabilities have been discovered in Google Chrome, which could allow for remote code execution. Successful exploitation of these vulnerabilities could allow for remote code execution in the context of the logged on user. 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.
