Last modified

CVE-2011-1923 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.31% chance of exploitation in the next 30 days.
