    Package        : curl
    CVE ID         : CVE-2018-16839 CVE-2018-16842
    
    Two vulnerabilities were discovered in cURL, an URL transfer library.
    
    CVE-2018-16839
    
        Harry Sintonen discovered that, on systems with a 32 bit size_t, an
        integer overflow would be triggered when a SASL user name longer
        than 2GB is used. This would in turn cause a very small buffer to be
        allocated instead of the intended very huge one, which would trigger
        a heap buffer overflow when the buffer is used.
    
    CVE-2018-16842
    
        Brian Carpenter discovered that the logic in the curl tool to wrap
        error messages at 80 columns is flawed, leading to a read buffer
        overflow if a single word in the message is itself longer than 80
        bytes.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 7.52.1-5+deb9u8.
    
    We recommend that you upgrade your curl packages.
