A 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. This patch is called 855a0853ad3abd4a6cd85ce06fce6d8d4c7a0b60. You should upgrade the affected component.
A flaw was found in libssh. A remote attacker could trigger an out-of-bounds read vulnerability in the SFTP Extension Name Handler by manipulating the idx argument in the sftp_extensions_get_name or sftp_extensions_get_data functions. This could lead to a Denial of Service (DoS), making the affected system unresponsive.
