Security Bulletin: Vulnerabilities in PHP affect IBM Chassis Management Module (CMM) (CVE-2013-4248, CVE-2013-6420, CVE-2014-2497, CVE-2014-4049)

Vulnerability Details

Summary

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

Vulnerability Details:

CVE-ID: CVE-2013-4248

Description: PHP could allow a remote attacker to conduct spoofing attacks, caused by an error when handling certificates that contain hostnames with NULL bytes. 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 spoof SSL servers.

Affected Versions: OpenSSL module in PHP before 5.4.18 and 5.5.x before 5.5.2
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/86429 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2013-6420

Description: PHP could allow a remote attacker to execute arbitrary code on the system, caused by an error in the asn1_time_to_time_t() function when parsing X.509 certificates. An attacker could exploit this vulnerability using a specially-crafted X.509 certificate to corrupt memory and execute arbitrary code on the system.

Affected Versions: PHP before 5.3.28, 5.4.x before 5.4.23, and 5.5.x before 5.5.7
CVSS Base Score: 9.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/89602 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVE-ID: CVE-2014-2497

Description: LibGD is vulnerable to a denial of service, caused by a NULL pointer dereference in the gdImageCreateFromXpm function. A remote attacker could exploit this vulnerability to cause the application to crash. Note: This vulnerability also affects PHP.

Affected Versions: PHP 5.4.26 and earlier
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91917 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-4049

Description: PHP is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by when parsing DNS TXT record. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

Affected Versions: PHP 5.6.0beta4 and earlier
CVSS Base Score: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93769 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:P)
