Gnome Gvfs vulnerabilities

CVE-2026-84268 [HIGH] CWE-122 CVE-2026-84268: A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause read_reply() to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing the operation to write past the intended boundaries.

CVE-2019-12448 [HIGH] CWE-362 CVE-2019-12448: An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c has race cond An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c has race conditions because the admin backend doesn't implement query_info_on_read/write.

CVE-2026-88924 [HIGH] CWE-367 CVE-2026-88924: A flaw was found in the admin backend of gvfs. The privileged gvfsd-admin daemon changes the ownersh A flaw was found in the admin backend of gvfs. The privileged gvfsd-admin daemon changes the ownership of newly created private D-Bus sockets by calling the link-following chown() function on a pathname inside a user-controlled directory. A local attacker can exploit this via a Time-of-Check Time-of-Use (TOCTOU) race condition and exchange the socket

CVE-2019-12447 [HIGH] CVE-2019-12447: An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles fi An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles file ownership because setfsuid is not used.

CVE-2019-12795 [HIGH] CWE-276 CVE-2019-12795: daemon/gvfsdaemon.c in gvfsd from GNOME gvfs before 1.38.3, 1.40.x before 1.40.2, and 1.41.x before daemon/gvfsdaemon.c in gvfsd from GNOME gvfs before 1.38.3, 1.40.x before 1.40.2, and 1.41.x before 1.41.3 opened a private D-Bus server socket without configuring an authorization rule. A local attacker could connect to this server socket and issue D-Bus method calls. (Note that the server socket only accepts a single connection, so the attacker would

CVE-2019-3827 [HIGH] CWE-863 CVE-2019-3827: An incorrect permission check in the admin backend in gvfs before version 1.39.4 was found that allo An incorrect permission check in the admin backend in gvfs before version 1.39.4 was found that allows reading and modify arbitrary files by privileged users without asking for password when no authentication agent is running. This vulnerability can be exploited by malicious programs running under privileges of users belonging to the wheel group to furt

CVE-2026-84269 [MEDIUM] CWE-122 CVE-2026-84269: A flaw was found in the AFP backend in gvfs. When mounting a share, a malicious AFP server can cause A flaw was found in the AFP backend in gvfs. When mounting a share, a malicious AFP server can cause the DSI read path to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the pre-sized reply buffer, causing the operation to access past the intended boundaries. This issue

CVE-2019-12449 [MEDIUM] CWE-755 CVE-2019-12449: An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles a An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles a file's user and group ownership during move (and copy with G_FILE_COPY_ALL_METADATA) operations from admin:// to file:// URIs, because root privileges are unavailable.

CVE-2026-28296 [MEDIUM] CVE-2026-28296: A flaw was found in the FTP GVfs backend 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 [MEDIUM] CVE-2026-28295: A flaw was found in the FTP GVfs backend 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.

CVE-2026-84267 [MEDIUM] CWE-908 CVE-2026-84267: A flaw was found in the SFTP backend in gvfs. When mounting a share, a malicious SFTP server can cau A flaw was found in the SFTP backend in gvfs. When mounting a share, a malicious SFTP server can cause read_string() to allocate a buffer with a certain length but the function does not verify that the buffer is completely filled, leaving the remainder of the buffer containing uninitialized heap contents. If the server sends a short FXP_HANDLE reply

CVE-2026-84270 [MEDIUM] CWE-125 CVE-2026-84270: A flaw was found in the MTP backend in gvfs. When reading a file from a mounted MTP device, do_read( A flaw was found in the MTP backend in gvfs. When reading a file from a mounted MTP device, do_read() in gvfsbackendmtp.c trusts the data length returned by the device without limiting it to the original size requested by the client. If a malicious MTP device responds with more bytes than requested, this unrestricted length is passed directly to mem
