Descriptions
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.
curl y libcurl en versiones anteriores a 7.50.2, cuando se construye con NSS y la librería libnsspem.so está disponible en tiempo de ejecución, permiten a atacantes remotos secuestrar la autenticación de una conexión TLS aprovechando la reutilización de un certificado cliente cargado previamente desde un archivo para una conexión para el que no se ha configurado ningún certificado, una vulnerabilidad diferente a 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.
The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. Security Fix: It was found that the libcurl library did not prevent TLS session resumption when the client certificate had changed. 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.
