    Ubuntu Security Notice USN-2591-1

    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)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.04:
      libcurl3                        7.38.0-3ubuntu2.2
      libcurl3-gnutls                 7.38.0-3ubuntu2.2
      libcurl3-nss                    7.38.0-3ubuntu2.2
    
    Ubuntu 14.10:
      libcurl3                        7.37.1-1ubuntu3.4
      libcurl3-gnutls                 7.37.1-1ubuntu3.4
      libcurl3-nss                    7.37.1-1ubuntu3.4
    
    Ubuntu 14.04 LTS:
      libcurl3                        7.35.0-1ubuntu2.5
      libcurl3-gnutls                 7.35.0-1ubuntu2.5

    Ubuntu 12.04 LTS:
      libcurl3                        7.22.0-3ubuntu4.14
      libcurl3-gnutls                 7.22.0-3ubuntu4.14
      libcurl3-nss                    7.22.0-3ubuntu4.14
