+ <p>The four libcurl functions curl_escape(), curl_easy_escape(),
+ curl_unescape and curl_easy_unescape perform string URL percent
+ escaping and unescaping. They accept custom string length inputs
+ in signed integer arguments.</p>
+ <p>The provided string length arguments were not properly checked
+ and due to arithmetic in the functions, passing in the length
+ 0xffffffff (2^32-1 or UINT_MAX or even just -1) would end up
+ causing an allocation of zero bytes of heap memory that curl
+ would attempt to write gigabytes of data into.</p>
