Problem: potential overflow in spell_soundfold_wsal()
Solution: Protect wres from buffer overflow, by checking the
length (Zdenek Dohnal)
Error: OVERRUN (CWE-119):
vim91/src/spell.c:3819: cond_const: Checking "reslen < 254" implies that
"reslen" is 254 on the false branch.
vim91/src/spell.c:3833: incr: Incrementing "reslen". The value of "reslen"
is now 255.
vim91/src/spell.c:3792: overrun-local: Overrunning array "wres" of 254
4-byte elements at element index 254 (byte offset 1019) using index
"reslen - 1" (which evaluates to 254).
3789| {
3790| // rule with '<' is used

/*
|
|
* spell.c: code for spell checking
|
|
*
|
|
* See spellfile.c for the Vim spell file format.
|
|
*
|
|
* The spell checking mechanism uses a tree (aka trie). Each node in the tree
|
|
* has a list of bytes that can appear (siblings). For each byte there is a
|
|
* pointer to the node with the byte that follows in the word (child).
|
|
*
|
|
* A NUL byte is used where the word may end. The bytes are sorted, so that
|
|
* binary searching can be used and the NUL bytes are at the start. The
|
|
* number of possible bytes is stored before the list of bytes.
|
|
*
|
|
* The tree uses two arrays: "byts" stores the characters, "idxs" stores
|
|
* either the next index or flags. The tree starts at index 0. For example,
|
|
* to lookup "vi" this sequence is followed:
|
|
* i = 0
|
|
* len = byts[i]
|
|
* n = where "v" appears in byts[i + 1] to byts[i + len]
|
|
* i = idxs[n]
|
|
* len = byts[i]
|
|
* n = where "i" appears in byts[i + 1] to byts[i + len]
|
|
* i = idxs[n]
|
|
* len = byts[i]
|
|
* find that byts[i + 1] is 0, idxs[i + 1] has flags for "vi".
|
|
*
|
|
* There are two word trees: one with case-folded words and one with words in
|
|
* original case. The second one is only used for keep-case words and is
|
|
* usually small.
|
|
*
|
|
* There is one additional tree for when not all prefixes are applied when
|
|
* generating the .spl file. This tree stores all the possible prefixes, as
|
|
* if they were words. At each word (prefix) end the prefix nr is stored, the
|
|
* following word must support this prefix nr. And the condition nr is
|
|
* stored, used to lookup the condition that the word must match with.
|
|
*
|
|
* Thanks to Olaf Seibert for providing an example implementation of this tree
|
|
* and the compression mechanism.
|
|
* LZ trie ideas:
|
|
* http://www.irb.hr/hr/home/ristov/papers/RistovLZtrieRevision1.pdf
|
|
* More papers: http://www-igm.univ-mlv.fr/~laporte/publi_en.html
|
|
*
|
|
* Matching involves checking the caps type: Onecap ALLCAP KeepCap.
|
|
*
|
|
* Why doesn't Vim use aspell/ispell/myspell/etc.?
