Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the sftp_handle() function due to an incorrect comparison check that allows access to memory beyond the valid handle list, resulting in the return of an invalid pointer used in further processing. An attacker can access unintended memory regions and potentially expose sensitive information or alter service behaviour by sending crafted requests after authenticating to the SFTP service.
