Security Bulletin

This security bulletin contains information about 10 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU16134

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2014-9912

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists due to boundary error when the get_icu_disp_value_src_php function in ext/intl/locale/locale_methods.c in PHP before 5.3.29, 5.4.x before 5.4.30, and 5.5.x before 5.5.14 does not properly restrict calls to the ICU uresbund.cpp component. A remote unauthenticated attacker can trigger buffer overflow and cause the service to crash via a locale_get_display_name call with a long first argument.

Mitigation

Update the affected packages.

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

Exploit availability: Yes

Description

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

The vulnerability exists due to infinite loop in zend/zend_exceptions.c in PHP, possibly 5.x before 5.6.28 and 7.x before 7.0.13. A remote attacker can trigger infinite loop and cause the service to crash via a crafted Exception object in serialized data.
