Vulnerability Name:

CVE-2006-7230 (CCN-38582)

Assigned:2007-11-15
Published:2007-11-15
Updated:2017-10-11
Summary:Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate the amount of memory needed for a compiled regular expression pattern when the (1) -x or (2) -i UTF-8 options change within the pattern, which allows context-dependent attackers to cause a denial of service (PCRE or glibc crash) via crafted regular expressions.
