CVE-2013-2061

The openvpndecrypt function in crypto.c in OpenVPN 2.3.0 and earlier, when running in UDP mode, allows remote attackers to obtain sensitive information via a timing attack involving an HMAC comparison function that does not run in constant time and a padding oracle attack on the CBC mode cipher...

CVE-2013-2061

OpenVPN 2.3.0 and earlier is affected in UDP mode due to two issues in crypto.c: (1) openvpn_decrypt uses an HMAC comparison that does not run in constant time, enabling timing-based information disclosure, and (2) a padding oracle risk in the CBC mode cipher. Exploitation could allow an unauthen...

FreeBSD : polarssl -- Timing attack against protected RSA-CRT implementation (ccefac3e-2aed-11e3-af10-000c29789cb5)

PolarSSL Project reports : The researchers Cyril Arnaud and Pierre-Alain Fouque investigated the PolarSSL RSA implementation and discovered a bias in the implementation of the Montgomery multiplication that we used. For which they then show that it can be used to mount an attack on the RSA key...
