Description

Flaws were discovered in the way PCRE handles certain malformed regular expressions. If an application linked against PCRE, such as Konqueror, parsed a malicious regular expression, it may have been possible to run arbitrary code as the user running the application. (CVE-2006-7225, CVE-2006-7226, CVE-2006-7228, CVE-2006-7230, CVE-2007-1660)
