Vulnerability Name:

CVE-2013-5915 (CCN-87661)

Assigned:2013-10-01
Published:2013-10-01
Updated:2013-10-31
Summary:The RSA-CRT implementation in PolarSSL before 1.2.9 does not properly perform Montgomery multiplication, which might allow remote attackers to conduct a timing side-channel attack and retrieve RSA private keys.
