Vulnerability Details:

CVE ID: CVE-2014-0015

Description: libcURL could allow a remote attacker from within the local network to bypass security restrictions, caused by the re-use of recently authenticated connections. By sending a new NTLM-authenticated request, an attacker could exploit this vulnerability to perform unauthorized actions with the privileges of the victim.

CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/90841 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVE ID: CVE-2014-0139

Description: cURL/libcURL could allow a remote attacker to bypass security restrictions, caused by an error in the hostmatch() function when validating certificates containing an IP address with a wildcard match within the Common Name field. By sending a specially-crafted SSL certificate containing wildcard characters, a remote attacker could exploit this vulnerability to spoof the server and launch further attacks on the system.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92130 for the current score
CVSS Environmental Score*: Undefined

CVE ID: CVE-2014-0138

Description: cURL/libcURL could allow a remote attacker to bypass security restrictions, caused by the re-use of previously used connections when processing new requests. An attacker could exploit this vulnerability to hijack the privileges of a different user's session and launch further attacks on the system.

CVSS Base Score: 6.4
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92131 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:P)

CVE ID: CVE-2014-2522

Description: cURL/libcURL allow a remote attacker to bypass restrictions, caused by the failure to properly verify SSL certificates. By persuading a victim to visit a specially-crafted Web site containing a malicious certificate, an attacker could exploit this vulnerability using man-in-the-middle techniques to launch further attacks on the system.
