------------------------------------------------------------------------- Debian LTS Advisory DLA-4513-1 [email protected] 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.
