Severity
Important
Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs: vim: * vim-X11-9.2.780-1.hum1 (aarch64, x86_64) * vim-common-9.2.780-1.hum1 (aarch64, x86_64) * vim-data-9.2.780-1.hum1 (noarch) * vim-default-editor-9.2.780-1.hum1 (noarch) * vim-enhanced-9.2.780-1.hum1 (aarch64, x86_64) * vim-filesystem-9.2.780-1.hum1 (noarch) * vim-minimal-9.2.780-1.hum1 (aarch64, x86_64) * xxd-9.2.780-1.hum1 (aarch64, x86_64) * vim-9.2.780-1.hum1.src (src)

A flaw was found in Vim, an open-source command-line text editor. A remote attacker could exploit this vulnerability by convincing a user to load a specially crafted spell file. This malicious file can trigger a stack out-of-bounds write, which corrupts the editor's memory and causes it to crash. This leads to a Denial of Service (DoS), making the editor unavailable to the user.

Impact Moderate

There is a security flaw in Vim. If you use Vim to open a malicious file written by a hacker, and you use the auto-complete feature while typing, the file can secretly force your computer to run unauthorized commands or malware.

Threats
Impact Important

A flaw was found in Vim, an open-source command-line text editor. The PHP omni-completion script improperly handles specially crafted input. When a victim opens a malicious PHP file and invokes omni-completion, an unescaped class or trait name can be interpreted as Ex commands. This allows a remote attacker to achieve arbitrary operating-system command execution.
