CVE-2016-5420

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...

lib32-curl: authentication bypass

A vulnerability was found in a way libcurl uses NTLM-authenticated proxy connections. Libcurl will reuse NTLM-authenticated proxy connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. Since NTLM-based authentication is...

CURL-CVE-2016-0755 NTLM credentials not-checked for proxy connection reuse

libcurl reuses NTLM-authenticated proxy connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. libcurl maintains a pool of connections after a transfer has completed. The pool of connections is then gone through when a ne...

curl: Negotiate not treated as connection-oriented
