==========================================================================

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

– Ubuntu 20.04 LTS
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS

Summary:

curl could be made to expose sensitive information over the network.

Software Description:
– curl: HTTP, HTTPS, and FTP client and client libraries

Details:

wrong destination, possibly exposing sensitive information.

libcurl3-gnutls 7.58.0-2ubuntu3.10
libcurl3-nss 7.58.0-2ubuntu3.10
libcurl4 7.58.0-2ubuntu3.10

libcurl3 7.47.0-1ubuntu2.16
