Summary
Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2026-28296: A flaw was found in the FTP GVfs backend. A remote attacker could exploit this input validation vulnerability by supplying specially crafted file paths containing carriage return and line feed (CRLF) sequences. These unsanitized sequences allow the attacker to terminate intended FTP commands and inject arbitrary FTP commands, potentially leading to arbitrary code execution or other severe impacts. CVE-2026-28295: A flaw was found in the FTP GVfs backend. A malicious FTP server can exploit this vulnerability by providing an arbitrary IP address and port in its passive mode (PASV) response. The client unconditionally trusts this information and attempts to connect to the specified endpoint, allowing the malicious server to probe for open ports accessible from the client's network.
