    Several vulnerabilities were discovered in cURL, an URL transfer library:
    
    CVE-2016-8615
    
        It was discovered that a malicious HTTP server could inject new
        cookies for arbitrary domains into a cookie jar.
    
    CVE-2016-8616
    
        It was discovered that when re-using a connection, curl was doing case
        insensitive comparisons of user name and password with the existing
        connections.
    
    CVE-2016-8617
    
        It was discovered that on systems with 32-bit addresses in userspace
        (e.g. x86, ARM, x32), the output buffer size value calculated in the
        base64 encode function would wrap around if input size was at least
        1GB of data, causing an undersized output buffer to be allocated.
    
    CVE-2016-8618
    
        It was discovered that the curl_maprintf() function could be tricked
        into doing a double-free due to an unsafe size_t multiplication on
        systems using 32 bit size_t variables.
    
    CVE-2016-8619
    
        It was discovered that that the Kerberos implementation could be
        tricked into doing a double-free when reading one of the length fields
        from a socket.
    
    CVE-2016-8620
    
        It was discovered that the curl tool's "globbing" feature could write
        to invalid memory areas when parsing invalid ranges.
    
    CVE-2016-8621
    
        It was discovered that the function curl_getdate could read out of
        bounds when parsing invalid date strings.
    
    CVE-2016-8622
    
        It was discovered that the URL percent-encoding decode function would
        return a signed 32bit integer variable as length, even though it
        allocated a destination buffer larger than 2GB, which would lead to
        a out-of-bounds write.
    
    CVE-2016-8623
    
        It was discovered that libcurl could access an already-freed memory
        area due to concurrent access to shared cookies. This could lead to
        a denial of service or disclosure of sensitive information.
    
    CVE-2016-8624
    
        It was discovered that curl wouldn't parse the authority component of
        a URL correctly when the host name part ends with a '#' character,
        and could be tricked into connecting to a different host.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 7.38.0-4+deb8u5.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 7.51.0-1.
    
    We recommend that you upgrade your curl packages.
