PoC Released for 20-Year Old PostgreSQL RCE Flaw

A public proof-of-concept exploit has been released for CVE-2026-2005, a critical heap-based buffer overflow vulnerability in PostgreSQL's pgcrypto extension, allowing full remote code execution and privilege escalation to the database superuser level. This vulnerability has existed since 2005 and was discovered by an AI-powered security tool during the ZeroDay.Cloud 2025 event in December 2025. An upstream patch was committed on February 8, 2026, and released on February 12, 2026. The vulnerability has a CVSS score of 8.8 and affects approximately 80% of cloud environments using PostgreSQL, with 45% accessible via the internet. The flaw is in the pgp_parse_pubenc_sesskey() function, which lacks bounds checking, allowing attackers to manipulate session key lengths. The pgcrypto extension can be installed by any database role with CREATE privileges, increasing the risk of exploitation. The proof-of-concept exploit involves an information leak, arbitrary write, and privilege escalation to remote code execution. The vulnerability affects all major versions of PostgreSQL prior to the February 2026 releases, which include versions 18.2, 17.8, 16.12, 15.16, and 14.21. Mitigation steps include upgrading to patched versions, restricting CREATE privileges, blocking direct internet exposure, rotating database credentials, auditing the usage of COPY FROM PROGRAM, and verifying patched engine versions for cloud-managed PostgreSQL users.

Yet Another Windows Update Done In By The EFI System Partition

The EFI System Partition (ESP) is an important part of modern computing that users are generally advised to avoid tampering with. Insufficient space on the EFI partition can lead to ambiguous error messages during updates, particularly with Microsoft’s security updates. The EFI partition is typically mapped to drive Y:, but may also be assigned to Z: or other letters. In some cases, such as transitioning from Windows 10 to Windows 11, users may need to access the EFI partition, where one solution involves removing TrueType Font (TTF) files under EFIMicrosoftBootFonts. However, caution is advised when handling the EFI partition, as mistakes can prevent the operating system from booting.

Windows CE Ported to Nintendo 64

Throaty Mumbo successfully ran Windows CE 2.11 on the Nintendo 64 by leveraging the shared architecture of both systems, which are based on the MIPS R4000 processor family. The project involved a month of reverse engineering, using Microsoft toolchains, custom hardware modifications, and debugging techniques. An EverDrive flash cartridge was used to load custom ROMs, and a USB connection facilitated uploads from a PC. Challenges included crashes with the initial EverDrive cartridge, which were resolved by upgrading to the EverDrive-64 X7. A custom kernel clone was created to troubleshoot issues with the stock Windows CE kernel, ultimately allowing the project to revert to the unmodified version. The Nintendo 64 controller was repurposed as a mouse, and standard Windows CE applications could be launched from the desktop. Comprehensive build details are available on GitHub.
