{"id":"CLSA-2026-1782896270","summary":"Fix CVE(s): CVE-2026-55693, CVE-2026-57455, CVE-2026-57456","details":"   * SECURITY UPDATE: Out-of-bounds write in tree_count_words() in src/spellfile.c when a crafted .spl/.sug spell-file pair loaded during spell suggestion drives the word-trie descent past the end of the MAXWLEN-sized arridx, curi and wordcount stack arrays\n     - debian/patches/CVE-2026-55693.patch: bound the descent in tree_count_words() and sug_filltree() with depth \u003c MAXWLEN - 1, matching the sibling trie walkers, so the depth index can no longer run past the fixed MAXWLEN-sized arrays\n     - CVE-2026-55693\n   * SECURITY UPDATE: Out-of-bounds write in spell_soundfold_sofo() in src/spell.c when a word longer than MAXWLEN is sound-folded through a spell file's SOFO byte map while a SOFO-based spell language is active, writing past the end of the caller's MAXWLEN-sized result buffer\n     - debian/patches/CVE-2026-57455.patch: bound the single-byte SOFO translation loop in spell_soundfold_sofo() with ri \u003c MAXWLEN - 1 so the output index can no longer run past the fixed MAXWLEN-sized result buffer\n     - CVE-2026-57455\n   * SECURITY UPDATE: Code execution via Python omni-completion inserting buffer-derived docstrings verbatim between triple quotes in the reconstructed source run through exec(), letting a crafted docstring break out of the triple-quoted literal and execute attacker-controlled code\n     - debian/patches/CVE-2026-57456.patch: use repr() to quote docstrings in the Scope, Class, and Function get_code() methods of python3complete and pythoncomplete so docstring text can no longer break out of the generated string literal\n     -
