Echo: vim: security update to 2:9.2.0858-1

medium Tenable Cloud Security Plugin ID 459168

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 9.2.0662, the dump_prefixes() function in
 src/spell.c walks a spell-file prefix trie iteratively with a depth counter while dumping the prefixes
 that apply to a word. 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 (prefix[], arridx[], curi[]). A
 crafted .spl file, loaded when the user dumps the word list, 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 9.2.0662. (CVE-2026-55892)

Solution

Update the vim library and its related packages to version 2:9.2.0858-1 or later.
