<p>cURL is a command line tool for transferring files with URL syntax,
|
|
supporting numerous protocols.

|
|
<p>Multiple vulnerabilities have been found in cURL:</p>
|
|
|
|
<ul>
|
|
<li>When zlib is enabled, the amount of data sent to an application for
|
|
automatic decompression is not restricted (CVE-2010-0734).
|
|
</li>
|
|
<li>When performing GSSAPI authentication, credential delegation is
|
|
always used (CVE-2011-2192).
|
|
</li>
|
|
<li>When SSL is enabled, cURL improperly disables the OpenSSL workaround
|
|
to mitigate an information disclosure vulnerability in the SSL and TLS
|
|
protocols (CVE-2011-3389).
|
|
</li>
|
|
<li>libcurl does not properly verify file paths for escape control
|
|
characters in IMAP, POP3 or SMTP URLs (CVE-2012-0036).
|
|
</li>
|
|
</ul>
|
|

|
|
<impact type="normal">
|
|
<p>A remote attacker could entice a user or automated process to open a
|
|
specially crafted file or URL using cURL, possibly resulting in the
|
|
remote execution of arbitrary code, a Denial of Service condition,
|
|
disclosure of sensitive information, or unwanted actions performed via
|
|
the IMAP, POP3 or SMTP protocols. Furthermore, remote servers may be able
|
|
to impersonate clients via GSSAPI requests.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All cURL users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.24.0"
|
|
</code>
