CVE-2011-4599

CWE-119Published: June 21, 2012· Updated: Jun 16, 2026

7.5

CVSS v3.1

Official Description

Stack-based buffer overflow in the _canonicalize function in common/uloc.c in International Components for Unicode (ICU) before 49.1 allows remote attackers to execute arbitrary code via a crafted locale ID that is not properly handled during variant canonicalization.

Technical Analysis

CVE-2011-4599 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
