Echo: vim: security update to 2:9.2.0858-1
high Tenable Cloud Security Plugin ID 462353
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Vim is an open source, command line text editor. Prior to 9.2.0653, the tree_count_words() function in
src/spellfile.c fills in the word-count fields of a spell-file word trie by walking it iteratively with a
depth counter. The counter is bounded only by the trie structure itself; it is never checked against the
size of the fixed MAXWLEN-element stack arrays it indexes (arridx[], curi[], wordcount[]). A crafted
.spl/.sug file pair, loaded when the user invokes spell suggestion, can drive the descent arbitrarily
deep, so the function writes past the end of those arrays. This is a stack out-of-bounds write that
corrupts the call frame and crashes the editor. This vulnerability is fixed in 9.2.0653. (CVE-2026-55693)
Solution
Update the vim library and its related packages to version 2:9.2.0858-1 or later.See Also
