========================================================================== Ubuntu Security Notice USN-4060-1 July 16, 2019
nss vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in NSS.
Software Description: - nss: Network Security Service library
Details:
Henry Corrigan-Gibbs discovered that NSS incorrectly handled importing certain curve25519 private keys. An attacker could use this issue to cause NSS to crash, resulting in a denial of service, or possibly obtain sensitive information. (CVE-2019-11719)
Hubert Kario discovered that NSS incorrectly handled PKCS#1 v1.5 signatures when using TLSv1.3. An attacker could possibly use this issue to trick NSS into using PKCS#1 v1.5 signatures, contrary to expectations. This issue only applied to Ubuntu 19.04. (CVE-2019-11727)
Jonas Allmann discovered that NSS incorrectly handled certain p256-ECDH public keys. An attacker could possibly use this issue to cause NSS to crash, resulting in a denial of service. (CVE-2019-11729)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 19.04: libnss3 2:3.42-1ubuntu2.1
Ubuntu 18.04 LTS: libnss3 2:3.35-2ubuntu2.3
Ubuntu 16.04 LTS: libnss3 2:3.28.4-0ubuntu0.16.04.6
After a standard system update you need to restart any applications that use NSS, such as Evolution, to make all the necessary changes.
