Summary:

Several security issues were fixed in curl.

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

Details:

Alex Nichols discovered that curl incorrectly handled NTLM authentication
credentials. A remote attacker could use this issue to cause curl to crash,
resulting in a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 16.04 LTS, Ubuntu 17.04 and Ubuntu 17.10.

It was discovered that curl incorrectly handled FTP wildcard matching. A
remote attacker could use this issue to cause curl to crash, resulting in a
denial of service, or possibly obtain sensitive information.
