Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Privilege escalation

EUVDB-ID: #VU16083

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-0185

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local attacker to gain elevated privileges. The weakness exists due to sapi/fpm/fpm/fpm_unix.c in the FastCGI Process Manager (FPM) in PHP before 5.4.28 and 5.5.x before 5.5.12 uses 0666 permissions for the UNIX socket. A local attacker can gain elevated privileges via a crafted FastCGI client.

Mitigation

Update the affected packages.

Vulnerable software versions

php5 (Ubuntu package): 5.3.2-1ubuntu4.1 - 5.3.10-1ubuntu3.11

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Denial of service

EUVDB-ID: #VU16084

Risk: Low

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-0237

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists in cdf_unpack_summary_info function in cdf.c in the Fileinfo component in PHP before 5.4.29 and 5.5.x before 5.5.13 due to performance degradation. A remote attacker can trigger many file_printf calls and cause the service to crash.

Mitigation

Update the affected packages.

No. We are not aware of malware exploiting this vulnerability.

3) Infinite loop

EUVDB-ID: #VU16085

Risk: Low

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-0238

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in the cdf_read_property_info function in cdf.c in the Fileinfo component in PHP before 5.4.29 and 5.5.x before 5.5.13. A remote attacker can trigger out-of-bounds memory access via a vector that (1) has zero length or (2) is too long and cause the service to crash.

Mitigation

Update the affected packages.

4) Heap-based buffer overflow

EUVDB-ID: #VU16086

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-4049

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

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

The vulnerability exists due to heap-based buffer overflow in the php_parserr function in ext/standard/dns.c. A remote attacker can trigger memory corruption via a crafted DNS TXT record, related to the dns_get_record function and cause the service to crash or 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.
