Guido Vranken discovered that FreeRADIUS, an open source implementation of RADIUS, the IETF protocol for AAA (Authorisation, Authentication, and Accounting), did not properly handle memory when processing packets. This would allow a remote attacker to cause a denial-of-service by application crash, or potentially execute arbitrary code.

All those issues are covered by this single DSA, but it’s worth noting that not all issues affect all releases :

  • CVE-2017-10978 and CVE-2017-10983 affect both jessie and stretch;

  • CVE-2017-10979, CVE-2017-10980, CVE-2017-10981 and CVE-2017-10982 affect only jessie;

  • CVE-2017-10984, CVE-2017-10985, CVE-2017-10986 and CVE-2017-10987 affect only stretch.
