curl and libcurl before 7.50.2, when built with NSS and the libnsspem.so library is available at runtime, allow remote attackers 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-2016-7141 [HIGH] curl vulnerabilities
Title: curl vulnerabilities
Summary: Several security issues were fixed in curl.
It was discovered that curl incorrectly reused client certificates when
built with NSS. A remote attacker could possibly use this issue to hijack
the authentication of a TLS connection. (CVE-2016-7141)
Nguyen Vu Hoang discovered that curl incorrectly handled escaping certain
strings. A remote attacker could possibly use this issue to cause curl to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2016-7167)
It was discovered that curl incorrectly handled storing cookies. A remote
attacker could possibly use this issue to inject cookies for arbitrary
domains in the cookie jar. (CVE-2016-8615)

curl: Incorrect reuse of client certificates
curl and libcurl before 7.50.2, when built with NSS and the libnsspem.so library is available at runtime, allow remote attackers 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.
It was found that the libcurl library using the NSS (Network Security Services) library as TLS/SSL backend incorrectly re-used client certificates for subsequent TLS connections in certain cases. An attacker could potentially use this flaw to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.

After testing original CVE-2016-5420 patch, it was discovered that libcurl built on top of NSS (Network Security Services) still incorrectly re-uses client certificates if a certificate from file is used for one TLS connection but no certificate is set for a subsequent TLS connection.
The original patch for CVE-2016-5420 has been amended to also contain the attached patch:
