Description Adam Mariš 2017-07-19 08:37:14 EDT
A buffer overflow can cause an open unsecured server to crash after 2GB (greater than 2147483711 bytes to trigger the software bug)) XML message is received. Fortunately, the overflowing data after 2GB is cleaned up in the buffer which means that the chances of exploiting this flaw (by injecting code) is significantly reduced in gSOAP versions affected.
