Title:	Debian: Security Advisory (DLA-3437-1)
Summary:	The remote host is missing an update for the Debian 'libssh' package(s) announced via the DLA-3437-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'libssh' package(s) announced via the DLA-3437-1 advisory. Vulnerability Insight: Two security issues have been discovered in libssh, a tiny C SSH library, which may allows an remote authenticated user to cause a denial of service or inject arbitrary commands. CVE-2019-14889 A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target. CVE-2023-1667 A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may allow an authenticated client to cause a denial of service. For Debian 10 buster, these problems have been fixed in version 0.8.7-1+deb10u2. We recommend that you upgrade your libssh packages.
