Summary

A potential stack buffer overwrite occurs on the SFTP server side when receiving a malicious packet that has a handle size larger than the system handle or file descriptor size, but smaller than the maximum allowed handle size.

Risk Assessment

This could lead to a stack buffer overflow, potentially enabling code execution or causing a denial of service on the SFTP server. It affects the availability and confidentiality of transmitted data.

Recommendation

Update the SFTP server software to a version containing the fix. Until then, restrict access to the SFTP server from untrusted networks.
