Debian Security Advisory DSA-3930-1                   security@debian.org

Package        : freeradius
CVE ID         : CVE-2017-10978 CVE-2017-10979 CVE-2017-10980 CVE-2017-10981 
                 CVE-2017-10982 CVE-2017-10983 CVE-2017-10984 CVE-2017-10985 
                 CVE-2017-10986 CVE-2017-10987
Debian Bug     : 868765

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.

For the oldstable distribution (jessie), these problems have been fixed
in version 2.2.5+dfsg-0.2+deb8u1.

For the stable distribution (stretch), these problems have been fixed in
version 3.0.12+dfsg-5+deb9u1.

We recommend that you upgrade your freeradius packages.
