Ubuntu Security Notice USN-3441-1

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

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

- Ubuntu 17.04
- 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:

Daniel Stenberg discovered that curl incorrectly handled large floating
point output. 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 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2016-9586)

Even Rouault discovered that curl incorrectly handled large file names when
doing TFTP transfers. A remote attacker could use this issue to cause curl
to crash, resulting in a denial of service, or possibly obtain sensitive
memory contents. (CVE-2017-1000100)

Brian Carpenter and Yongji Ouyang discovered that curl incorrectly handled
numerical range globbing. A remote attacker could use this issue to cause
curl to crash, resulting in a denial of service, or possibly obtain
sensitive memory contents. (CVE-2017-1000101)

Max Dymond discovered that curl incorrectly handled FTP PWD responses. A
remote attacker could use this issue to cause curl to crash, resulting in a
denial of service. (CVE-2017-1000254)

Brian Carpenter discovered that curl incorrectly handled the --write-out
command line option. A local attacker could possibly use this issue to
obtain sensitive memory contents. (CVE-2017-7407)
