Proof of concept code that demonstrates how the Windows kernel suffers from a privilege escalation vulnerability due to a double-fetch in PspBuildCreateProcessContext that leads to a stack buffer overflow.

View CSAF 1. EXECUTIVE SUMMARY CVSS v4 8.5 ATTENTION: Low attack complexity Vendor: Delta Electronics Equipment: CNCSoft-G2 DOPSoft Vulnerability: Stack-based Buffer Overflow 2. RISK EVALUATION Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of Delta Electronics CNCSoft-G2, a Human-Machine Interface (HMI) software, are affected: CNCSoft-G2: Versions 2.0.0.5 (with DOPSoft v5.0.0.93) and prior 3.2 Vulnerability Overview 3.2.1 STACK-BASED BUFFER OVERFLOW CWE-121 Delta Electronics CNCSoft-G2 lacks proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. CVE-2024-4192 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H ). A C...

Ubuntu Security Notice 6744-3 - USN-6744-1 fixed a vulnerability in Pillow. This update provides the corresponding updates for Ubuntu 24.04 LTS. Hugo van Kemenade discovered that Pillow was not properly performing bounds checks when processing an ICC file, which could lead to a buffer overflow. If a user or automated system were tricked into processing a specially crafted ICC file, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code.
