Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications.
Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.
The following packages have been upgraded to a later upstream version: nss (3.53.1), nspr (4.25.0). (BZ#1809549, BZ#1809550)
Security Fix(es):
nss: UAF in sftk_FreeSession due to improper refcounting (CVE-2019-11756)
nss: Check length of inputs for cryptographic primitives (CVE-2019-17006)
nss: Side channel vulnerabilities during RSA key generation (CVE-2020-12402)
nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state (CVE-2019-17023)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
