Description Vincent Danen 2011-03-18 18:09:13 UTC

It was reported [1] that the compression code for MaraDNS contained a programming error where allocating an array of integers was allocated in bytes instead of sizeof(int) units.  This resulted in a buffer being too small, allowing it to be overwritten by sending MaraDNS a specially-crafted packet, which could crash MaraDNS.

MaraDNS 1.4.06 and 1.3.07.11 was released to correct this problems.  A patch to correct the flaw is included in the original report.
