| Description: | Summary:
The remote host is missing an update for the Debian 'curl' package(s) announced via the DLA-1568-1 advisory.
Vulnerability Insight:
Several vulnerabilities were discovered in cURL, an URL transfer library.
CVE-2016-7141
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 CVE-2016-5420.
CVE-2016-7167
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.
CVE-2016-9586
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.
CVE-2018-16839
Curl is vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service.
CVE-2018-16842
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.
For Debian 8 Jessie, these problems have been fixed in version 7.38.0-4+deb8u13.
We recommend that you upgrade your curl packages.
