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

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

– Ubuntu 15.04
– Ubuntu 14.10
– Ubuntu 14.04 LTS
– Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in curl.

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

Details:

Paras Sethia discovered that curl could incorrectly re-use NTLM HTTP
credentials when subsequently connecting to the same host over HTTP.
(CVE-2015-3143)

Hanno Böck discovered that curl incorrectly handled zero-length host names.
If a user or automated system were tricked into using a specially crafted
host name, an attacker could possibly use this issue to cause curl to
crash, resulting in a denial of service, or possibly execute arbitrary
code. This issue only affected Ubuntu 14.10 and Ubuntu 15.04.
(CVE-2015-3144)

Hanno Böck discovered that curl incorrectly handled cookie path elements.
If a user or automated system were tricked into parsing a specially crafted
cookie, an attacker could possibly 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, Ubuntu 14.10 and Ubuntu 15.04.
(CVE-2015-3145)

Isaac Boukris discovered that when using Negotiate authenticated
connections, curl could incorrectly authenticate the entire connection and
not just specific HTTP requests. (CVE-2015-3148)

Yehezkel Horowitz and Oren Souroujon discovered that curl sent HTTP headers
both to servers and proxies by default, contrary to expectations. This
issue only affected Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-3153)
