MitreCVELIST:CVE-2007-1661CVE-2007-1661
Perl-Compatible Regular Expression (PCRE) library before 7.3 backtracks too far when matching certain input bytes against some regex patterns in non-UTF-8 mode, which allows context-dependent attackers to obtain sensitive information or cause a denial of service (crash), as demonstrated by the “\X?\d” and “\P{L}?\d” patterns.
