Vulnerability Summary for CVE-2007-4782

Original release date: 09/10/2007
Last revised: 08/21/2010
Source: US-CERT/NIST

Overview

PHP before 5.2.3 allows context-dependent attackers to cause a denial of service (application crash) via (1) a long string in the pattern parameter to the glob function; or (2) a long string in the string parameter to the fnmatch function, accompanied by a pattern parameter value with undefined characteristics, as demonstrated by a "*[1]e" value. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless these issues can be demonstrated for code execution.
