+ <p>CVE-2019-5435: Integer overflows in curl_url_set()</p>
+ <p>libcurl contains two integer overflows in the curl_url_set()
+ function that if triggered, can lead to a too small buffer
+ allocation and a subsequent heap buffer overflow.</p>
+ <p>The flaws only exist on 32 bit architectures and require
+ excessive string input lengths.</p>
+ <p>CVE-2019-5436: TFTP receive buffer overflow</p>
+ <p>libcurl contains a heap buffer overflow in the function
+ (tftp_receive_packet()) that recevives data from a TFTP server. It
+ calls recvfrom() with the default size for the buffer rather than
+ with the size that was used to allocate it. Thus, the content that
+ might overwrite the heap memory is entirely controlled by the server.</p>
+ <p>The flaw exists if the user selects to use a "blksize" of 504 or
+ smaller (default is 512). The smaller size that is used, the larger
+ the possible overflow becomes.</p>
+ <p>Users chosing a smaller size than default should be rare as the
+ primary use case for changing the size is to make it larger.</p>
+ <p>It is rare for users to use TFTP across the Internet. It is most
+ commonly used within local networks.</p>
+ <p>.</p>
