The complete control of the client is\nmade by the programmer. With libssh, you can remotely execute programs, transfer\nfiles, use a secure and transparent tunnel for your remote programs. With its\nSecure FTP implementation, you can play with remote files easily, without\nthird-party programs others than libcrypto (from openssl).\r\n\r\n\nSecurity Fix(es):\n\nA weakness has been identified in libssh up to 0.11.3. The impacted element is the function sftp_extensions_get_name/sftp_extensions_get_data of the file src/sftp.c of the component SFTP Extension Name Handler. Executing a manipulation of the argument idx can lead to out-of-bounds read. The attack may be performed from remote. Upgrading to version 0.11.4 and 0.12.0 is sufficient to resolve this issue.
