Description Josh Bressers 2005-02-22 14:04:47 UTC

Multiple stack-based buffer overflows in libcURL and cURL 7.12.1, and
possibly other versions, allow remote malicious web servers to execute
arbitrary code via base64 encoded replies that exceed the intended
buffer lengths when decoded, which is not properly handled by (1) the
Curl_input_ntlm function in http_ntlm.c during NTLM authentication or
(2) the Curl_krb_kauth and krb4_auth functions in krb4.c during
Kerberos authentication.
