The Perl_reg_numbered_buff_fetch function in Perl 5.10.0, 5.12.0,
5.14.0, and other versions, when running with debugging enabled,
allows context-dependent attackers to cause a denial of service
(assertion failure and application exit) via crafted input that
is not properly handled when using certain regular expressions,
as demonstrated by causing SpamAssassin and OCSInventory to
crash.
