This would allow an unauthenticated remote attacker to cause a denial of service (crash of the KDC daemon) by sending maliciously crafted packets. For the stable distribution (stretch), this problem has been fixed in version 7.1.0+dfsg-13+deb9u2. We recommend that you upgrade your heimdal packages. For the detailed security status of heimdal please refer to its security tracker page at: https://security-tracker.debian.org/tracker/heimdal Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org - -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEAqSkbVtrXP4xJMh3EL6Jg/PVnWQFAloo8VsACgkQEL6Jg/PV nWQsrQgAkOt019q15yl6Ctx1SzWHNT0NfOFybG8WzMp1TZ3JzjsoRUSffymWKceB mJiuim5J+5se2+bVEMkblsXuNmbqnn1EaTwZ6XjI41J5Kv+/2qvbGsosvGP8JdTB 0cHWgSyNTaV8mwD745AoctIN8BL/5lxO3r7LjC8Mpw+W7l3XjhK6SfGL2QHd65BY 6K2r1hHTypOM3iLSNnWC2nR9/4OK5RU2JBvK9kjP4cRJJzZX7JacR53tO/+bY4eL 5fEzXexh97jNW7M5svJtCsdyoEwauAtkIl6noLGTs+K/a8afw8VU0gDQfTD35d3H e+rG1WMEv0H1tYQGdIKOGqtWYuNQKQ== =iHQJ - -----END PGP SIGNATURE----- - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
