Posted by Benjamin D. Thomas   
Mandrake Tavis Ormandy, of the Google Security Team, discovered that ncompress, when uncompressing data, performed no bounds checking, which could allow a specially crafted datastream to underflow a .bss buffer with attacker controlled data. Updated packages have been patched to correct this issue.
