Vulnerability from fkie_nvd - Published: 2012-06-20 17:55 - Updated: 2026-06-16 23:30
Severity
Summary
The Diffie-Hellman key-exchange implementation in dhm.c in PolarSSL before 0.14.2 does not properly validate a public parameter, which makes it easier for man-in-the-middle attackers to obtain the shared secret key by modifying network traffic, a related issue to CVE-2011-5095.
