+ set_sofo()
+
+Problem: [security]: heap buffer overflow in set_sofo()
+ (Yazan Balawneh)
+Solution: Reset sl_sal_first (Yasuhiro Matsumoto).
+
+A crafted spell file with an empty SN_SAL section before an SN_SOFO
+section reaches set_sofo() with sl_sal_first[] already set to -1 by
+set_sal_first(). The counting loop then under-counts colliding
+multi-byte "from" characters, allocates an undersized list and writes
+past its end.
