cURL is a command line tool and library for transferring files via
|
|
many different protocols. It supports NTLM authentication to retrieve
|
|
files from Windows-based systems.

iDEFENSE reported that insufficient bounds checking on a memcpy()
|
|
of the supplied NTLM username can result in a stack overflow.

<impact type="normal">
|
|
<p>
|
|
A remote attacker could setup a malicious server and entice an
|
|
user to connect to it using a cURL client, potentially leading to the
|
|
execution of arbitrary code with the permissions of the user running
|
|
cURL.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable NTLM authentication by not using the --anyauth or --ntlm
|
|
options when using cURL (the command line version). Workarounds for
|
|
programs that use the cURL library depend on the configuration options
|
|
presented by those programs.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All cURL users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.15.0"</code>
|
|
</resolution>
