Bugs: #82534
ID: 200503-20

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"
