An update that solves four vulnerabilities can now be installed.

## Description:

This update for gvfs fixes the following issues:

  * CVE-2026-84267: `read_string()` allocates buffers withouth verifying that
    the buffer is completely filled when communicating with a malicious SFTP
    server, which can lead to uninitialized heap memory leaks (bsc#1278157).
  * CVE-2026-84268: `read_reply()` processes length that exceeds requested
    client size when communicating with a malicious SFTP server, which can lead
    to an OOB write (bsc#1278158).
  * CVE-2026-84269: DSI read path processes length that exceeds requested client
    size when communicating with a malicious AFP server, which can lead to an
    OOB memory access (bsc#1278159).
  * CVE-2026-84270: `do_read()` trusts the data length returned by a mounted MTP
    device and does not limit it to the original size requested by the client,
    which can lead to an OOB write (bsc#1278156).
