Security Bulletin

This security bulletin contains information about 9 vulnerabilities.

1) Reachable assertion

EUVDB-ID: #VU16087

Risk: Low

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2014-0207

CWE-ID: CWE-617 - Reachable Assertion

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to assertion failure in the cdf_read_short_sector function in cdf.c in file before 5.19, as used in the Fileinfo component in PHP before 5.4.30 and 5.5.x before 5.5.14. A remote attacker can trigger reachable assertion via a specially crafted CDF file and cause the service to crash.

Mitigation

Update the affected packages.

6) Type Confusion

EUVDB-ID: #VU16092

Risk: High

CVSSv4.0: 8.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2014-3515

CWE-ID: CWE-843 - Type confusion

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a type confusion error in (1) ArrayObject and (2) SPLObjectStorage. when the SPL component in PHP before 5.4.30 and 5.5.x before 5.5.14 incorrectly anticipates that certain data structures will have the array data type after unserialization. A remote attacker can trigger a type confusion error via a crafted string that triggers use of a Hashtable destructor and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.

9) Type Confusion

EUVDB-ID: #VU16095

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2014-4721

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

Description

The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The vulnerability exists due to a type confusion error when the phpinfo implementation in ext/standard/info.c in PHP before 5.4.30 and 5.5.x before 5.5.14 does not ensure use of the string data type for the PHP_AUTH_PW, PHP_AUTH_TYPE, PHP_AUTH_USER, and PHP_SELF variables. A local attacker can use the integer data type with crafted values, as demonstrated by reading a private SSL key in an Apache HTTP Server web-hosting environment with mod_ssl and a PHP 5.3.x mod_php and obtain sensitive information.

Mitigation

Update the affected packages.
