- Summary
- Fix CVE(s): CVE-2026-55693, CVE-2026-55892, CVE-2026-57455, CVE-2026-57456
- Details
-
- SECURITY UPDATE: out-of-bounds write parsing a crafted spell file:
tree_count_words() and sug_filltree() descended the word trie without
bounding the recursion depth, so a deeply nested trie wrote past the
ends of their MAXWLEN-sized arridx[], curi[] and wordcount[] arrays.
- debian/patches/CVE-2026-55693.patch: only descend while depth < MAXWLEN - 1 in both trie walkers, in src/spell.c; matches upstream patch 9.2.0653.
- CVE-2026-55693
- SECURITY UPDATE: stack out-of-bounds write in dump_prefixes() when
dumping spell prefixes (:spelldump): the word trie was descended
without bounding the recursion depth, overflowing the MAXWLEN-sized
prefix[], arridx[] and curi[] arrays.
- debian/patches/CVE-2026-55892.patch: only descend while depth < MAXWLEN - 1, in src/spell.c; matches upstream patch 9.2.0662.
- CVE-2026-55892
- SECURITY UPDATE: out-of-bounds write in soundfold(): the single-byte
branch of spell_soundfold_sofo() wrote one result byte per input byte
into the MAXWLEN-sized res[] buffer with no bound, so a long word
overflowed it.
- debian/patches/CVE-2026-57455.patch: stop the translation loop once ri reaches MAXWLEN - 1, in src/spell.c; matches upstream patch 9.2.0698.
- CVE-2026-57455
- SECURITY UPDATE: arbitrary code execution in the python and python3
omni-completion plugins: reconstructed class/function definitions ran
through exec() embedded buffer-supplied docstrings inside a triple-
quoted Python string literal, so a docstring containing a closing
triple-quote broke out of the literal and executed attacker code.
- debian/patches/CVE-2026-57456.patch: quote docstrings with repr() instead of triple-quoting, in runtime/autoload/python3complete.vim and pythoncomplete.vim; matches upstream patch 9.2.0699.
- CVE-2026-57456
- SECURITY UPDATE: out-of-bounds write parsing a crafted spell file:
tree_count_words() and sug_filltree() descended the word trie without
bounding the recursion depth, so a deeply nested trie wrote past the
ends of their MAXWLEN-sized arridx[], curi[] and wordcount[] arrays.
