    Several vulnerabilities were discovered in cURL, an URL transfer library:
    
    CVE-2015-3143
    
        NTLM-authenticated connections could be wrongly reused for requests
        without any credentials set, leading to HTTP requests being sent
        over the connection authenticated as a different user. This is
        similar to the issue fixed in DSA-2849-1.
    
    CVE-2015-3144
    
        When parsing URLs with a zero-length hostname (such as "http://:80"),
        libcurl would try to read from an invalid memory address. This could
        allow remote attackers to cause a denial of service (crash). This
        issue only affects the upcoming stable (jessie) and unstable (sid)
        distributions.
    
    CVE-2015-3145
    
        When parsing HTTP cookies, if the parsed cookie's "path" element
        consists of a single double-quote, libcurl would try to write to an
        invalid heap memory address. This could allow remote attackers to
        cause a denial of service (crash). This issue only affects the
        upcoming stable (jessie) and unstable (sid) distributions.
    
    CVE-2015-3148
    
        When doing HTTP requests using the Negotiate authentication method
        along with NTLM, the connection used would not be marked as
        authenticated, making it possible to reuse it and send requests for
        one user over the connection authenticated as a different user.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 7.26.0-1+wheezy13.
    
    For the upcoming stable distribution (jessie), these problems have been
    fixed in version 7.38.0-4+deb8u1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 7.42.0-1.
    
    We recommend that you upgrade your curl packages.
