Vulnerability Details

Abstract

Security vulnerabilities in Open SSL, OpenSSH and curl affect the Integrated Management Module II (IMM2).

Vulnerability Details

CVE-ID: CVE-2014-2653

Description: OpenSSH could allow a remote attacker to bypass security restrictions, caused by an error in the SSH client when handling a HostCertificate. By persuading a victim to visit a specially-crafted Web site containing a malicious certificate, an attacker could exploit this vulnerability using a malicious server to disable SSHFP-checking.

CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/92116&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-2532

Description: OpenSSH could allow a remote attacker to bypass security restrictions, caused by the inclusion of wildcard characters in the AcceptEnv lines of the sshd_config configuration file within the sshd program. By using a substring before a wildcard character, an attacker could exploit this vulnerability to bypass intended environment restrictions.

CVSS Vector: (AV:N/AC:L/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.

CVE-ID: CVE-2014-4545

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.

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.

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.

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.

CVE-ID: CVE-2014-3509

Description: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl_parse_serverhello_tlsext() code. If a multithreaded client connects to a malicious server using a resumed session, a remote attacker could exploit this vulnerability to cause a denial of service.

CVE-ID: CVE-2014-3511

Description: OpenSSL could allow a remote attacker to bypass security restrictions, caused by the negotiation of TLS 1.0 instead of higher protocol versions by the OpenSSL SSL/TLS server code when handling a badly fragmented ClientHello message. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to TLS 1.0.
