Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-3532-1)
Summary:	The remote host is missing an update for the Debian 'openssh' package(s) announced via the DLA-3532-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'openssh' package(s) announced via the DLA-3532-1 advisory. Vulnerability Insight: It was discovered that OpenSSH incorrectly handled loading certain PKCS#11 providers. If a user forwarded their ssh-agent to an untrusted system, a remote attacker could possibly use this issue to load arbitrary libraries from the user's system and execute arbitrary code. In addition to the above security issue, this update also fixed another bug - bad interaction between the ssh_config ConnectTimeout and ConnectionAttempts directives - connection attempts after the first attempt were ignoring the requested timeout. More details about this can be found at [link moved to references])18. For Debian 10 buster, this problem has been fixed in version 1:7.9p1-10+deb10u3. We recommend that you upgrade your openssh packages. For the detailed security status of openssh please refer to its security tracker page at: [link moved to references] Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references] Affected Software/OS: 'openssh' package(s) on Debian 10. Solution: Please install the updated package(s). CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
