Package : nss
Version : 2:3.42.1-1+deb10u7
CVE ID : CVE-2020-25648 CVE-2023-4421
Multiple vulnerabilities were found in nss, a set of libraries designed
to support cross-platform development of security-enabled client and
server applications.
CVE-2020-25648
A flaw was discovered in how NSS handles CipherChangeSpec messages
in TLS 1.3. It could allow an attacker to send multiple CCS
messages to servers compiled against NSS, causing denial-of-service.
CVE-2023-4421
A fuzzing project discovered vulnerabilities to Bleichenbacher
timing attacks in NSS's facilities for RSA cryptography.
For Debian 10 buster, these problems have been fixed in version
2:3.42.1-1+deb10u7.
We recommend that you upgrade your nss packages.
