NVD Description

Note: Versions mentioned in the description apply only to the upstream libssh-config package and not the libssh-config package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

A flaw was found in libssh in which a malicious SFTP (SSH File Transfer Protocol) server can exploit this by sending a malformed 'longname' field within an SSH_FXP_NAME message during a file listing operation. This missing null check can lead to reading beyond allocated memory on the heap. This can cause unexpected behavior or lead to a denial of service (DoS) due to application crashes.
