May 2025 Third-Party Patches: Notable Vulnerabilities and Updates
In May 2025, 79 vulnerable applications received 129 updates. These updates remediate 107 unique vulnerabilities. In other words, May isn’t that different from previous months. This month, prioritize zero-day vulnerabilities and those with high Exploit Prediction Scoring System (EPSS) scores.

Notable Vulnerabilities in May 2025 Third-Party Patches
There were two zero-day vulnerabilities in May. CVE-2025-27363 is a dependency vulnerability affecting Gpg4win (GNU Privacy Guard for Windows) caused by FreeType in 2.13.0 and below. An out-of-bounds write can occur when parsing font subglyph structures for TrueType GX and variable fonts. The code assigns a signed short to an unsigned long, adds a static value, and causes a wraparound, leading to inadequate heap buffer allocation. For more details, see the Gpg4win release notes and the NVD entry.
CVE-2025-4664 is a zero-day flaw that affects several Chromium-based products, including Electron, Microsoft Edge for Business, Google Chrome, Vivaldi, Brave Browser, Burp Suite, and Opera One. A vulnerability in the Loader component of Google Chrome prior to version 136.0.7103.113 allowed remote attackers to exploit insufficient policy enforcement, leading to the potential leakage of cross-origin data through a specially crafted HTML page. For more information, refer to the Google Chrome release notes.
The Exploit Prediction Scoring System (EPSS) scores for the two zero-days are 0.68 and 0.024. Given these scores, prioritize patching these two vulnerabilities first. Another high-risk issue is CVE-2023-48795, affecting TurboVNC, with an EPSS score of 0.67. The flaw originates in a dependency used by OpenSSH before 9.6 (and other products) and can let remote attackers bypass integrity checks. For more information, consult the TurboVNC release notes and NVD entry.
