Descriptions

The ConnectionExists function in lib/url.c in libcurl before 7.47.0 does not properly re-use NTLM-authenticated proxy connections, which might allow remote attackers to authenticate as other users via a request, a similar issue to CVE-2014-0015.

La función ConnectionExists en lib/url.c en libcurl en versiones anteriores a 7.47.0 no reutiliza correctamente las conexiones proxy autenticadas por NTML, lo que podría permitir a atacantes remotos autenticarse como otros usuarios a través de una petición, un problema similar a CVE-2014-0015.
