Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-3187-1)
Summary:	The remote host is missing an update for the Debian 'dropbear' package(s) announced via the DLA-3187-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'dropbear' package(s) announced via the DLA-3187-1 advisory. Vulnerability Insight: An issue was discovered in Dropbear, a relatively small SSH server and client. Due to a non-RFC-compliant check of the available authentication methods in the client-side SSH code, it was possible for an SSH server to change the login process in its favor. This attack can bypass additional security measures such as FIDO2 tokens or SSH-Askpass. Thus, it allows an attacker to abuse a forwarded agent for logging on to another server unnoticed. For Debian 10 buster, this problem has been fixed in version 2018.76-5+deb10u2. We recommend that you upgrade your dropbear packages. For the detailed security status of dropbear 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: 'dropbear' package(s) on Debian 10. Solution: Please install the updated package(s). CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:C/A:N
