Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.10 - Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

NSS could be made to crash or run programs if it received specially crafted input.

Software Description: - nss: Network Security Service library

Details:

It was discovered that NSS incorrectly handled certain memory operations. A remote attacker could use this issue to cause NSS to crash, resulting in a denial of service, or possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.10:
libnss3 2:3.45-1ubuntu2.1

Ubuntu 19.04:
libnss3 2:3.42-1ubuntu2.3
