Descriptions

curl, as shipped in Red Hat Enterprise Linux 6 before version 7.19.7-53, did not correctly backport the fix for CVE-2015-3148 because it did not reflect the fact that the HAVE_GSSAPI define was meanwhile substituted by USE_HTTP_NEGOTIATE. This issue was introduced in RHEL 6.7 and affects RHEL 6 curl only.

curl, tal y como se distribuye en Red Hat Enterprise Linux 6, en versiones anteriores a la 7.19.7-53, no realizó correctamente el backport de la solución para CVE-2015-3148 debido a que no reflejó el hecho de que la definición HAVE_GSSAPI se sustituyó mientras tanto por USE_HTTP_NEGOTIATE. Este problema se introdujo en RHEL 6.7 y solo afecta a RHEL 6 curl.

It was found that the fix for CVE-2015-3148 in curl was incomplete. An application using libcurl with HTTP Negotiate authentication could incorrectly re-use credentials for subsequent requests to the same server.

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 fix for CVE-2015-3148 in curl was incomplete. An application using libcurl with HTTP Negotiate authentication could incorrectly re-use credentials for subsequent requests to the same server.
