CWE-119Published: February 18, 2008· Updated: Jun 16, 2026
7.5
CVSS v3.1
Official Description
Buffer overflow in PCRE before 7.6 allows remote attackers to execute arbitrary code via a regular expression containing a character class with a large number of characters with Unicode code points greater than 255.
Technical Analysis
CVE-2008-0674 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.
