The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. Security Fix: * Multiple integer overflow flaws leading to heap-based buffer overflows were found in the way curl handled escaping and unescaping of data. An attacker could potentially use these flaws to crash an application using libcurl by sending a specially crafted input to the affected libcurl functions.
