- ----------------------------------------------------------------------- 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----- iQIzBAEBCAAdFiEEbJ0QSEqa5Mw4X3xxgj6WdgbDS5YFAmNxaG4ACgkQgj6WdgbD S5a8DxAAwCRGu+BrK9fZGoZdGO0fRNyFF3KxPOZxSNFk/crm3IH9lf7JMzbXTpSo L3g8kDmCIIq6piPn2PNstLV1eBfHvjFswNj8712JcECiHFMiTWu72zwtbuhKPTRO y3L66Kz8sCBRrK0uGoVZbnTQgSZJ0cnM8LcUDIN+2ELkrPO6zY2ZyfCsW/c6o3ZC s8rGBGWQ5Cjgj1fjF+6NnooxgQcI6pyquWLGXdUs8tkZx+aABL2uCxtqlqaeomje kCPLpyG5xz6Ui9xuPfMwzRG/NcDIfAtFpCciPXN2NLgrflGZadrMgBluM3YvUcXn 57eE9Zz2hII+ChZ64KcH765MWQxJ5C9hgONKWTh5lFLasAMO068EBFb8Svan19w1 yrnaWxFyIg71bOCObRDV2imOsqiKjKvdzlgTEI2JAepAHAskjNFbO4iBHkgfJ9Wu jW/Rr2X1Axyx/KkduUsm0htCo+++REb+9eqDM/hWYmWlQ94RPOUxolQCp8teKQ5P QSlP/wH8nVkIGHDxmD93PudpH0tMVbzZeUApevKsBuUAns6X76yVvhxkSe1n38Kd q603iA/RRAx+7buIlMNOZDRWLxluVPRr3U7jXuYwG35wGSZ69spgOjlT2kK0jQ13 EN55CiHyr7fjZpSjL0cHcK3jphIBqXAjsN0EkuqE+a2VfjlTZiA= =df9d -----END PGP SIGNATURE-----
