Vulnerability Details


CVE-ID: CVE-2014-3638

DESCRIPTION: D-Bus is vulnerable to a denial of service, caused by an error related to method call replies. By sending the maximum number of parallel method calls, a local attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 2.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/96009 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:N/I:N/A:P)


CVE-ID: CVE-2014-3639

DESCRIPTION: D-Bus is vulnerable to a denial of service, caused by an error related to incomplete connections. By making repeated connection attempts, a local attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 2.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/96010 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:N/I:N/A:P)


CVE-ID: CVE-2014-3477

DESCRIPTION: D-Bus is vulnerable to a denial of service, caused by an error in the dbus-daemon. By sending an activation message, a local attacker could exploit this vulnerability to cause a memory leak and a denial of service.

CVSS Base Score: 2.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/93760 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:N/I:N/A:P)


CVE-ID: CVE-2014-5459

DESCRIPTION: PHP Pear could allow a local attacker to launch a symlink attack. The PEAR_REST class in REST.php creates temporary files insecurely. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to various files on the system, which could allow the attacker to write to arbitrary files on the system with elevated privileges.

CVSS Base Score: 3.3
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/95480 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:M/Au:N/C:N/I:P/A:P)


CVE-ID: CVE-2014-4721

DESCRIPTION: PHP could allow a remote attacker to obtain sensitive information, caused by an error in the /ext/standard/info.c file when handling multiple variables. An attacker could exploit this vulnerability to obtain the SSL RSA key and other sensitive information.

CVSS Base Score: 5.0
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/94287 for more information

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)


CVE-ID: CVE-2014-3597

DESCRIPTION: PHP is vulnerable to a heap-based buffer overflow, caused by an incomplete fix related to improper bounds checking 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.

CVSS Base Score: 7.5
