DESCRIPTION
 cURL[1] is a client to get/put files from/to servers, using any of
 the supported protocols.
 
 This announcement fixes a remote buffer overflow vulnerability[2] in
 cURL that could allow a malicious servers to execute arbitrary code
 via base64 encoded replies that exceed the intended buffer lengths
 when decoded, which is not properly handled by the Curl_input_ntlm
 function in http_ntlm.c during NTLM authentication or the
 Curl_krb_kauth and krb4_auth functions in krb4.c during Kerberos
 authentication.


SOLUTION
 It is recommended that all cURL users upgrade their packages.
 
 IMPORTANT: In order to properly close the vulnerability, all
 applications liked against libcurl should also be restart.
