Description Sam James archtester gentoo-dev Security 2020-10-26 07:22:11 UTC
From release notes for 3.2:
* SECURITY ISSUE: Attempted to make RSA PKCS#1v1.5 decryption more constant
time, to protect against Bleichenbacher vulnerabilities. Due to limitations
imposed by our API, we cannot completely mitigate this vulnerability and a
future release will contain a new API which is designed to be resilient to
these for contexts where it is required. Credit to Hubert Kario for
reporting the issue. CVE-2020-25659
