Amazon Linux AMI : curl (ALAS-2016-730)

high Nessus Plugin ID 93008

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

curl and libcurl before 7.50.1 do not prevent TLS session resumption when the client certificate has changed, which allows remote attackers to bypass intended restrictions by resuming a session. (CVE-2016-5419)

curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.
(CVE-2016-5420)

libcurl before 7.50.1 allows attackers to control which connection is used or possibly have unspecified other impact via unknown vectors.
(CVE-2016-5421)

Solution

Run 'yum update curl' to update your system.
