Last modified

CVE-2006-7226 is a vulnerability of currently unknown severity. Perl-Compatible Regular Expression (PCRE) library before 6.7 does not properly calculate the compiled memory allocation for regular expressions that involve a quantified "subpattern containing a named recursion or subroutine reference," which allows context-dependent attackers to cause a denial of service (error or crash).. EPSS estimates a 1.60% chance of exploitation in the next 30 days.
