Package        : curl
CVE ID         : CVE-2015-3143 CVE-2015-3144 CVE-2015-3145 CVE-2015-3148

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 ""),
    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.
