CVE-2006-7230: Pcre

Medium severity, CVSS 4.3. EPSS: 1.7% chance of exploitation in the next 30 days.

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.

Affected products
