CVSS 8.8 · High EPSS 0,36%

Kerentanan Heap-based Buffer Overflow. Skor CVSS 3.1 8.8 (High) menurut redhat.com.

Deskripsi (NVD)

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.
