Without this patch, BusyBox handles bash pattern substitutions without a terminating '/' character incorrectly. Consider the following shell script: _bootstrapver=5.0.211-r0 _referencesdir="/usr/${_bootstrapver/-*}/Sources" echo $_referencesdir This should output `/usr/5.0.211/Sources`. However, without this patch it instead outputs `/usr/5.0.211Sources`. This is due to the fact that BusyBox expects the bash pattern substitutions to always be terminated with a '/' (at least in this part of subvareval) and thus reads passed the substitution itself and consumes the '/' character which is part of the literal string. If there is no '/' after the substitution then BusyBox might perform an out-of-bounds read under certain circumstances. When replacing the bash pattern substitution with `${_bootstrapver/-*/}`, or with this patch applied, ash outputs the correct value.
