22) Link following

EUVDB-ID: #VU41567

Risk: Medium

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2014-3981

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

acinclude.m4, as used in the configure script in PHP 5.5.13 and earlier, allows local users to overwrite arbitrary files via a symlink attack on the /tmp/phpglibccheck file.

Mitigation

Update the affected packages.
dev-lang/php to version: 5.5.16

23) Heap-based buffer overflow

EUVDB-ID: #VU16086

Risk: High

CVSSv4.0: 8.1 [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:U/U:Amber]

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.

24) Use-after-free

EUVDB-ID: #VU16093

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2014-4670

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local attacker to cause DoS condition.

The vulnerability exists due to use-after-free error in ext/spl/spl_dllist.c in the SPL component in PHP through 5.5.14. A local attacker can trigger memory corruption via crafted iterator usage within applications in certain web-hosting environments and cause the service to crash.

Mitigation

Update the affected packages.
dev-lang/php to version: 5.5.16

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.

25) Input validation error

EUVDB-ID: #VU32501

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2014-5120

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

gd_ctx.c in the GD component in PHP 5.4.x before 5.4.32 and 5.5.x before 5.5.16 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to overwrite arbitrary files via crafted input to an application that calls the (1) imagegd, (2) imagegd2, (3) imagegif, (4) imagejpeg, (5) imagepng, (6) imagewbmp, or (7) imagewebp function.

Mitigation

Update the affected packages.
