FKIE_CVE-2005-4872
Vulnerability from fkie_nvd - Published: 2005-12-31 05:00 - Updated: 2026-06-16 22:19
Severity
Summary
Perl-Compatible Regular Expression (PCRE) library before 6.2 does not properly count the number of named capturing subpatterns, which allows context-dependent attackers to cause a denial of service (crash) via a regular expression with a large number of named subpatterns, which triggers a buffer overflow. NOTE: this issue was originally subsumed by CVE-2006-7224, but that CVE has been REJECTED and split.
