FKIE_CVE-2007-4771
Vulnerability from fkie_nvd - Published: 2008-01-29 00:00 - Updated: 2026-06-16 22:44
Severity
Summary
Heap-based buffer overflow in the doInterval function in regexcmp.cpp in libicu in International Components for Unicode (ICU) 3.8.1 and earlier allows context-dependent attackers to cause a denial of service (memory consumption) and possibly have unspecified other impact via a regular expression that writes a large amount of data to the backtracking stack. NOTE: some of these details are obtained from third party information.
