Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1792217772 advisory.

- vim is vulnerable to Use After Free (CVE-2021-4187)

- Vim is an open source, command line text editor. Prior to 9.2.0479, a command injection vulnerability exists in tar#Vimuntar() in runtime/autoload/tar.vim when decompressing .tgz archives on Unix-like systems. The function builds :!gunzip and :!gzip -d commands using shellescape(tartail) without the {special} flag, allowing a crafted archive filename to trigger Vim cmdline-special expansion and execute shell commands in the user's context. This vulnerability is fixed in 9.2.0479. (CVE-2026-46483)

- Vim is an open source, command line text editor. Prior to 9.2.0845, StructMembers() in runtime/autoload/ccomplete.vim constructs and executes a vimgrep command using an insufficiently escaped typeref: or typename: value from a tags file, allowing an unterminated collection followed by a command separator to execute arbitrary Ex and operating-system commands when a user invokes C omni-completion with CTRL-X CTRL-O on a member access whose type is resolved from that tags file. This issue is fixed in version 9.2.0845. (CVE-2026-73073)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1792217772.
