Details

USN-4665-1 fixed several vulnerabilities in curl. This update provides
the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory details:

Varnavas Papaioannou discovered that curl incorrectly handled FTP PASV
responses. An attacker could possibly use this issue to trick curl into
connecting to an arbitrary IP address and be used to perform port scanner
and other information gathering. (CVE-2020-8284)

It was discovered that curl incorrectly handled FTP wildcard matchins. A
remote attacker could possibly use this issue to cause curl to consume
resources and crash, resulting in a denial of service. (CVE-2020-8285)
