CVE-2013-5915
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.

Does this matter?
Lower severity and a low EPSS score (2.14%). Track it; it rarely justifies an emergency change on its own.
