A Vulnerability in Mozilla PDF.js Could Allow for Arbitrary Code Execution

Read Time:32 Second

A vulnerability has been discovered in Mozilla PDF.js could allow for arbitrary code execution. Mozilla PDF.js is a PDF viewer that is built into Mozilla Firefox and can be used by other web browsers. Exploitation of this vulnerability could allow for arbitrary 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 less rights on the system could be less impacted than those who operate with administrative user rights.

USN-6765-1: Linux kernel (OEM) vulnerabilities

Read Time:3 Minute, 33 Second

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel
did not properly validate H2C PDU data, leading to a null pointer
dereference vulnerability. A remote attacker could use this to cause a
denial of service (system crash). (CVE-2023-6356, CVE-2023-6535,
CVE-2023-6536)

Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida
discovered that the Linux kernel mitigations for the initial Branch History
Injection vulnerability (CVE-2022-0001) were insufficient for Intel
processors. A local attacker could potentially use this to expose sensitive
information. (CVE-2024-2201)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux
kernel contained an out-of-bounds read vulnerability. An attacker could use
this to possibly cause a denial of service (system crash). (CVE-2024-23849)

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to a null pointer dereference vulnerability. A
privileged local attacker could use this to possibly cause a denial of
service (system crash). (CVE-2024-24860)

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