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
Install update from vendor's website.
