Title
Gvfs: gvfs-admin socket ownership race permits local root
Summary
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 pathname with a symbolic link pointing to an arbitrary root-owned file (such as /etc/pam.d/su). The daemon subsequently follows the symlink and changes the ownership of the targeted root-owned file to the attacker's user ID. This allows an authenticated local attacker to modify critical system files, leading to a full local privilege escalation to root.

Title
Gvfs: mtp: out-of-bounds read in do_read()
Summary
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 memcpy(). This causes the operation to read memory outside the intended boundaries. This allows an attacker who plugs in a malicious MTP device to cause a segmentation fault when a file is read and crash the gvfsd-mtp process, resulting in a denial of service.

Title
Gvfs: afp: heap-based buffer overflow in dsi read path
Summary
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 allows a malicious server to overflow a heap buffer and crash the gvfsd-afp process, resulting in a denial of service.

Title
Gvfs: sftp: heap-based buffer overflow in read_reply()
Summary
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. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution.

Title
Gvfs: sftp: uninitialized heap disclosure in read_string()
Summary
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, these uninitialized bytes are taken as the file handle. The client will then echo these uninitialized bytes back to the server on all subsequent requests using that handle. With a length of 128 bytes, this issue allows the malicious server to deterministically read uninitialized heap memory from the gvfsd-sftp process, leaking its heap base and the load address of the libgio library, resulting in a deterministic defeat of Address Space Layout Randomization (ASLR).

Summary
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 have to discover the server and connect to the socket before its owner does.)
Severity
No CVSS data available.

CVE-2019-3827 (GCVE-0-2019-3827)
Vulnerability from nvd – Published: 2019-03-25 17:47 – Updated: 2024-08-04 19:19
VLAI
EPSS
VEX
Summary
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 further escalate its privileges by modifying system files without user's knowledge. Successful exploitation requires uncommon system configuration.

Title
Gvfs: gvfs-admin socket ownership race permits local root
Summary
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 pathname with a symbolic link pointing to an arbitrary root-owned file (such as /etc/pam.d/su). The daemon subsequently follows the symlink and changes the ownership of the targeted root-owned file to the attacker's user ID. This allows an authenticated local attacker to modify critical system files, leading to a full local privilege escalation to root.

Title
Gvfs: mtp: out-of-bounds read in do_read()
Summary
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 memcpy(). This causes the operation to read memory outside the intended boundaries. This allows an attacker who plugs in a malicious MTP device to cause a segmentation fault when a file is read and crash the gvfsd-mtp process, resulting in a denial of service.

Title
Gvfs: afp: heap-based buffer overflow in dsi read path
Summary
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 allows a malicious server to overflow a heap buffer and crash the gvfsd-afp process, resulting in a denial of service.

Title
Gvfs: sftp: uninitialized heap disclosure in read_string()
Summary
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, these uninitialized bytes are taken as the file handle. The client will then echo these uninitialized bytes back to the server on all subsequent requests using that handle. With a length of 128 bytes, this issue allows the malicious server to deterministically read uninitialized heap memory from the gvfsd-sftp process, leaking its heap base and the load address of the libgio library, resulting in a deterministic defeat of Address Space Layout Randomization (ASLR).

Title
Gvfs: sftp: heap-based buffer overflow in read_reply()
Summary
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. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution.

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. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution."

Summary
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 have to discover the server and connect to the socket before its owner does.)
Severity
No CVSS data available.

Summary
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 further escalate its privileges by modifying system files without user's knowledge. Successful exploitation requires uncommon system configuration.
