[原文]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.

Synopsis
========

curl is vulnerable to a buffer overflow which could lead to the
execution of arbitrary code.

Background
==========

curl is a command line tool for transferring files via many different
protocols.

Affected packages
=================

    -------------------------------------------------------------------
     Package        /  Vulnerable  /                        Unaffected
    -------------------------------------------------------------------
  1  net-misc/curl      < 7.13.1                             >= 7.13.1

Description
===========

curl fails to properly check boundaries when handling NTLM
authentication.

Impact
======

With a malicious server an attacker could send a carefully crafted NTLM
response to a connecting client leading to the execution of arbitrary
code with the permissions of the user running curl.

Workaround
==========

Disable NTLM authentication by not using the --anyauth or --ntlm
options.

Resolution
==========

All curl users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/curl-7.13.1"

cURL / libcURL NTLM Authentication Curl_input_ntlm() Function Overflow
Context Dependent Input Manipulation
Loss of Integrity Upgrade
Exploit Unknown Vendor Verified

- 漏洞描述

cURL/libcURL contains an overflow condition in the NTLM authentication functionality. The issue is due to the 'Curl_input_ntlm()' function not validating user-supplied input. With a specially crafted request, a context-dependent attacker can cause a stack-based buffer overflow, resulting in a denial of service or potentially execution of arbitrary code.

- 漏洞讨论

It has been reported that cURL and libcURL are vulnerable to a remotely exploitable stack-based buffer overflow vulnerability. The cURL and libcURL Kerberos authentication code fails to ensure that a buffer overflow cannot occur when server response data is decoded.

The overflow occurs in the stack region, and remote code execution is possible if the saved instruction pointer is overwritten with a pointer to embedded instructions.

- 漏洞利用
