-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - ----------------------------------------------------------------------- Debian LTS Advisory DLA-3187-1 [email protected] https://www.debian.org/lts/security/ Utkarsh Gupta November 14, 2022 https://wiki.debian.org/LTS - -----------------------------------------------------------------------
Package : dropbear Version : 2018.76-5+deb10u2 CVE ID : CVE-2021-36369 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: https://security-tracker.debian.org/tracker/dropbear Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEbJ0QSEqa5Mw4X3xxgj6WdgbDS5YFAmNxacIACgkQgj6WdgbD S5b5QA//ccWLlO3tWt+By8byK8Ij/JDMFJLYqyUeactXN5LZPU8auiTLvt9KP+U1 8ONBg1ag/p3RDeViuMOL84++jKuOZl3q5av1lNPrylmme/4k+VfkXc1/t+dTr96e bvXx3Kqz9EvmIylEoe+lqonlsnQYJGKY8UM1x85o7tqMb5Xe9sY4dLroQFR3EMuV 1+g/hgyuxyd9i35CBq4L+YhQOZTf5Pl5dbv7hYwInCMgiJCuNQNQZxW4lObf/zGh r8xCJnJsMHVsm6KGzSEuA3AtsJt6WGMxU4jtimpSy/XUNlHUP494mcQA4GEUSXbQ +82j+BIgAQ6Fh4AzsEXKH51N5m+KHeex4i9nhwbke+IiByQll1Ro+jlHZsxP4Ptx pKug07pYrrJDvN2ClBjcs5nKHjibPj1wehmxVX94mxKaktPut5w+3Bjwm2Id0gbX z+jBIWlEUR3644AFQcr14gizekiKmMfui/4/Cn2/RIBQ0qofwKW0JhDe0Jsz+kP8 hLs9ryR+G9fBKC/c3vBhkgkbkvruHXRuUpJGl7XIL0PVL9WCCAo6igXWIsqY3WeJ B7wDyijY4xhf845qwUifd4qZzR+26N1A3vF+RS+Vhd7mYi9Gx8Wmg0izvOOal9GE 8mKu5O/SPa7Q1YsOo0sd+RG9U3/InX96pwZ7uV6I3NRtB4PZD70= =Sjht -----END PGP SIGNATURE-----
