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.
