Original description
The description as published by the source.
ytnef through 2.1.2 contains a heap out-of-bounds read vulnerability in MAPIPrint() that allows attackers to read past heap allocations by supplying compressed RTF properties. Attackers can deliver a crafted winmail.dat whose decompressed RTF lacks a NUL terminator, causing printf to over-read, crashing ytnefprint and leaking adjacent heap bytes.
