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 B=C3=B6ck 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 B=C3=B6ck discovered that curl incorrectly handled cookie path elem=
ents.
If a user or automated system were tricked into parsing a specially craft=
ed
cookie, an attacker could possibly use this issue to cause curl to crash,=

resulting in a denial of service, or possibly execute arbitrary code. Thi=
s
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 an=
d
not just specific HTTP requests. (CVE-2015-3148)

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