<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>Several vulnerabilities were discovered in cURL, an URL transfer
library.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2016-7141">CVE-2016-7141</a>
<p>When built with NSS and the libnsspem.so library is available at
runtime, allows an remote attacker to hijack the authentication of a
TLS connection by leveraging reuse of a previously loaded client
certificate from file for a connection for which no certificate has
been set, a different vulnerability than <a href="https://security-tracker.debian.org/tracker/CVE-2016-5420">CVE-2016-5420</a>.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2016-7167">CVE-2016-7167</a>
<p>Multiple integer overflows in the (1) curl_escape, (2)
curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape
functions in libcurl allow attackers to have unspecified impact via
a string of length 0xffffffff, which triggers a heap-based buffer
overflow.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2016-9586">CVE-2016-9586</a>
<p>Curl is vulnerable to a buffer overflow when doing a large floating
point output in libcurl's implementation of the printf() functions.
If there are any applications that accept a format string from the
outside without necessary input filtering, it could allow remote
attacks.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2018-16839">CVE-2018-16839</a>
<p>Curl is vulnerable to a buffer overrun in the SASL authentication
code that may lead to denial of service.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2018-16842">CVE-2018-16842</a>
<p>Curl is vulnerable to a heap-based buffer over-read in the
tool_msgs.c:voutf() function that may result in information exposure
and denial of service.</p></li>
</ul>
<p>For Debian 8 <q>Jessie</q>, these problems have been fixed in version
7.38.0-4+deb8u13.</p>
<p>We recommend that you upgrade your curl packages.</p>
