The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4513 advisory.

    -------------------------------------------------------------------------     Debian LTS Advisory DLA-4513-1                debian-lts@lists.debian.org     https://www.debian.org/lts/security/                   Andreas Henriksson     March 28, 2026                                https://wiki.debian.org/LTS

    Package        : gvfs     Version        : 1.46.2-2+deb11u1     CVE ID         : CVE-2026-28295 CVE-2026-28296     Debian Bug     : 1129285 1129286

    Codean Labs found that gvfs, a virtual filesystem implementation, was     affected by multiple vulnerabililies including FTP bounce attack     which could lead to probing open ports on client network and     improper CRLF validation which could allow an attacker to inject arbitrary FTP     commands.

    CVE-2026-28295

        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.

    CVE-2026-28296

        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.

    For Debian 11 bullseye, these problems have been fixed in version     1.46.2-2+deb11u1.

    We recommend that you upgrade your gvfs packages.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.
