Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Stack-based buffer overflow
EUVDB-ID: #VU7352
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-2017-11362
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code.
The weakness exists due to stack buffer overflow in line 142 when parsing locale in msgfmt_parse_message(). A remote attacker can trigger an error when passing overtly long slocale into libicu's umsg_open() that may lead to out-of-bounds write and execute arbitrary code with web server privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.
dev-lang/php to version: 5.6.31 or 7.0.23.
Gentoo Linux: All versions
CPE2.3 External linkshttps://security.gentoo.org/glsa/201709-21
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Stack-based buffer overflow
EUVDB-ID: #VU7356
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-2017-11628
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition or potentially execute arbitrary code.
The weakness exists due to stack buffer overflow in PHP INI parsing API 2 when handling malicious input. A remote attacker can send specially crafted data, trigger stack buffer overflow in zend_ini_do_op() that may lead to out-of-bounds write, cause the application to crash or execute arbitrary code with web server privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.
dev-lang/php to version: 5.6.31 or 7.0.23.
Gentoo Linux: All versions

No. We are not aware of malware exploiting this vulnerability.
3) Heap use-after-free error
EUVDB-ID: #VU8137
Risk: Medium
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:Green]
CVE-ID: CVE-2017-12932
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to improper use of the hash API for key deletion in a situation with an invalid array size. A remote attacker can use untrusted data to trigger heap use-after-free error in ext/standard/var_unserializer.re and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.
dev-lang/php to version: 5.6.31 or 7.0.23.
