vulnerability analysis and mitigation

A stack-based buffer overflow vulnerability (CVE-2025-29840) was discovered in Windows Media, disclosed on May 13, 2025. The vulnerability affects various Windows Media components and allows unauthorized attackers to execute code remotely over a network (NVD, Wiz).

The vulnerability is classified as a stack-based buffer overflow (CWE-121) and out-of-bounds write (CWE-787), with a CVSS v3.1 base score of 8.8 (HIGH). The CVSS vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H indicates that the vulnerability can be exploited over the network, requires low attack complexity, needs no privileges, but does require user interaction (NVD).

The vulnerability presents a significant security risk as it enables unauthorized attackers to execute malicious code remotely through the Windows Media component. Successful exploitation could result in attackers gaining control over the affected system with the capability to execute arbitrary code (Wiz).

Microsoft has addressed this vulnerability by releasing security updates as part of the May 2025 Patch Tuesday. Users and system administrators are strongly recommended to immediately apply these updates through Windows Update or enterprise management tools to secure their systems (Wiz).
