ID CVE-2006-7226

    description From Red Hat Security Advisory 2007:1068 : Updated pcre packages that resolve several security issues are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. PCRE is a Perl-compatible regular expression library. Flaws were discovered in the way PCRE handles certain malformed regular expressions. If an application linked against PCRE, such as Konqueror, parses 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-2007-1659) Users of PCRE are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. Red Hat would like to thank Ludwig Nussel for reporting these issues.

    description Multiple vulnerabilities were discovered by Tavis Ormandy and Will Drewry in the way that pcre handled certain malformed regular expressions. If an application linked against pcre, such as Konqueror, parses a malicious regular expression, it could lead to the execution of arbitrary code as the user running the application. Updated packages have been patched to prevent this issue. Additionally, Corporate Server 4.0 was updated to pcre version 6.7 which corrected CVE-2006-7225, CVE-2006-7226, CVE-2006-7227, CVE-2006-7228, and CVE-2006-7230.
