+ <background>
+ <p>cURL is a command line tool for transferring files with URL syntax,
+ supporting numerous protocols.
+ </p>
+ </background>
+ <description>
+ <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>
+ </description>
+ <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 "&gt;=net-misc/curl-7.24.0"
+ </code>
