    CVE ID         : CVE-2018-1000120 CVE-2018-1000121 CVE-2018-1000122
    
    Multiple vulnerabilities were discovered in cURL, an URL transfer library.
    
    CVE-2018-1000120
    
        Duy Phan Thanh discovered that curl could be fooled into writing a
        zero byte out of bounds when curl is told to work on an FTP URL with
        the setting to only issue a single CWD command, if the directory part
        of the URL contains a "%00" sequence.
    
    CVE-2018-1000121
    
        Dario Weisser discovered that curl might dereference a near-NULL
        address when getting an LDAP URL due to the ldap_get_attribute_ber()
        fuction returning LDAP_SUCCESS and a NULL pointer. A malicious server
        might cause libcurl-using applications that allow LDAP URLs, or that
        allow redirects to LDAP URLs to crash.
    
    CVE-2018-1000122
    
        OSS-fuzz, assisted by Max Dymond, discovered that curl could be
        tricked into copying data beyond the end of its heap based buffer
        when asked to transfer an RTSP URL.
    
    For the oldstable distribution (jessie), these problems have been fixed
    in version 7.38.0-4+deb8u10.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 7.52.1-5+deb9u5.
    
    We recommend that you upgrade your curl packages.
