## Description

Vim is an open source, command line text editor. Prior to 9.2.0846,
set\_sofo() in src/spellfile.c reuses sl\_sal\_first[] without resetting
values left by set\_sal\_first(), so a crafted spell file containing an
SN\_SAL section before an SN\_SOFO section causes under-counted mapping lists
and attacker-influenced writes beyond a heap allocation. This issue is
fixed in version 9.2.0846.
