5 | The Perl_reg_numbered_buff_fetch function in Perl 5.10.0, 5.12.0, | ||
6 | 5.14.0, and other versions, when running with debugging enabled, | ||
7 | allows context-dependent attackers to cause a denial of service | ||
8 | (assertion failure and application exit) via crafted input that | ||
9 | is not properly handled when using certain regular expressions, | ||
10 | as demonstrated by causing SpamAssassin and OCSInventory to | ||
11 | crash. | ||
