CVE-2018-9426
In RsaKeyPairGenerator::getNumberOfIterations of RSAKeyPairGenerator.java, an incorrect implementation could cause weak RSA key pairs being generated.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
