Security Bulletin: Vulnerabilities in curl affect IBM Chassis Management Module (CMM) (CVE-2013-4545, CVE-2014-0015, CVE-2014-0138, CVE-2014-0139, CVE-2013-2174)

Vulnerability Details

Summary

Multiple vulnerabilities in curl affect IBM Chassis Management Module (CMM).

Vulnerability Details

CVE-ID: CVE-2013-4545

Description: cURL/libcURL could allow a remote attacker to conduct spoofing attacks, caused by the improper validation of connection host name in TLS/SSL server certificates when the digital signature verification is disabled. By persuading a victim to visit a Web site containing a specially-crafted certificate, a remote attacker could exploit this vulnerability using man-in-the-middle techniques to cause the victim to accept spoofed certificates.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/89181 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

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

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 current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:P)

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 current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2013-2174

Description: cURL/libcURL is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the curl_easy_unescape() function in lib/escape.c. While decoding URL encoded strings to raw binary data, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
