Red Hat Security Advisory: vim security update
Multiple security vulnerabilities have been identified in Vim (Vi IMproved), including several arbitrary code execution flaws and denial of service conditions. These issues arise from crafted directory names, Python omni-completion, step-definition patterns, malicious docstrings, PHP files, and tags files, as well as out-of-bounds writes in spell file processing. Red Hat has issued an important security advisory with updates for affected versions of Red Hat Enterprise Linux 10.0 Extended Update Support and related variants.
AI Analysis
Technical Summary
This advisory addresses multiple vulnerabilities in Vim that allow arbitrary code execution and denial of service. The flaws include CVE-2026-47162 (arbitrary code execution via crafted directory names), CVE-2026-52858 (arbitrary code execution via Python omni-completion), CVE-2026-47167 (arbitrary code execution via crafted step-definition patterns), CVE-2026-57455 (denial of service via stack out-of-bounds write in spell_soundfold_sofo()), CVE-2026-57456 (arbitrary code execution via malicious docstrings in Python omni-completion), CVE-2026-55693 (out-of-bounds write in spell file word count), CVE-2026-59856 (arbitrary code execution via crafted PHP file in omni-completion), and CVE-2026-59858 (arbitrary command execution via crafted tags file in C omni-completion). These vulnerabilities affect Vim packages distributed with Red Hat Enterprise Linux 10.0 Extended Update Support and related architectures. The advisory provides updated packages to remediate these issues.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code or cause a denial of service condition on affected systems running vulnerable versions of Vim. This could compromise system integrity and availability. The advisory rates the security impact as Important (high severity).
Mitigation Recommendations
Red Hat has released updated Vim packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 10.0 Extended Update Support and related variants should apply the provided security updates promptly. For detailed update instructions, refer to the Red Hat advisory at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patches.
