Ubuntu Security Notice USN-3648-1
May 16, 2018

curl vulnerabilities
==========================================================================

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

- Ubuntu 18.04 LTS
- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in curl.

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

Details:

Dario Weisser discovered that curl incorrectly handled long FTP server
command replies. If a user or automated system were tricked into connecting
to a malicious FTP server, 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 17.10 and Ubuntu 18.04 LTS.
(CVE-2018-1000300)

Max Dymond discovered that curl incorrectly handled certain RTSP responses.
If a user or automated system were tricked into connecting to a malicious
server, a remote attacker could use this issue to cause curl to crash,
resulting in a denial of service, or possibly obtain sensitive information.
(CVE-2018-1000301)
