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.</p> <p><strong>Affected:</strong> Ubuntu:Pro:16.04:LTS: gvfs, Ubuntu:Pro:18.04:LTS: gvfs, Ubuntu:Pro:20.04:LTS: gvfs, Ubuntu:22.04:LTS: gvfs, Ubuntu:24.04:LTS: gvfs, Ubuntu:26.04:LTS: gvfs</p> <p>A flaw was found in the SFTP backend in gvfs.
