Ecosystem: Amazon Linux

Summary

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2026-34982: A modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file. The complete, guitabtooltip and printheader options are missing the P_MLE flag, allowing a modeline to be executed. Additionally, the mapset() function lacks a check_secure() call, allowing it to be abused from sandboxed expressions. An attacker who can deliver a crafted file to a victim achieves arbitrary command execution with the privileges of the user running Vim.
