CVE-2007-1660: Buffer Overflow
First published: Tue Oct 02 2007(Updated: )
Perl-Compatible Regular Expression (PCRE) library before 7.0 does not properly calculate sizes for unspecified "multiple forms of character class", which triggers a buffer overflow that allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code.
