Description Ville Skyttä 2007-11-20 19:50:19 UTC

http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-4767

"Perl-Compatible Regular Expression (PCRE) library before 7.3 does not properly
compute the length of (1) a \p sequence, (2) a \P sequence, or (3) a \P{x}
sequence, which allows context-dependent attackers to cause a denial of service
(infinite loop or crash) or execute arbitrary code."

F7 ships pcre 7.0.
