If an application using libcurl established an NTLM-authenticated connection to a server, and sent subsequent unauthenticated requests to the same server, the unauthenticated requests could be sent over the NTLM-authenticated connection, appearing as if they were sent by the NTLM authenticated user. (CVE-2015-3143)

It was discovered that libcurl could incorrectly reuse Negotiate authenticated HTTP connections for subsequent requests. If an application using libcurl established a Negotiate authenticated HTTP connection to a server and sent subsequent requests with different credentials, the connection could be re-used with the initial set of credentials instead of using the new ones. (CVE-2015-3148)

It was discovered that libcurl did not properly process cookies with a specially crafted 'path' element. If an application using libcurl connected to a malicious HTTP server sending specially crafted 'Set-Cookies' headers, this could lead to an out-of-bounds read, and possibly cause that application to crash. (CVE-2015-3145)

It was discovered that libcurl did not properly process zero-length host names. If an attacker could trick an application using libcurl into processing zero-length host names, this could lead to an out-of-bounds read, and possibly cause that application to crash. (CVE-2015-3144)");
