CVE-2016-2848: A packet with malformed options can trigger an assertion failure in ISC BIND versions

  • 7018170
  • 19-Oct-2016
  • 20-Dec-2016

Environment

SUSE Linux Enterprise Server 10 Service Pack 4  (SLES 10 SP4)
SUSE Linux Enterprise Server 10 Service Pack 3  (SLES 10 SP3)

Situation

A packet with a malformed options section can be used to deliberately trigger an assertion failure affecting versions of BIND which do not contain change #3548, which was first included in ISC BIND 9 releases in May 2013.
 
Current ISC versions of BIND are safe from this vulnerability, but repackaged versions distributed by other parties may be vulnerable if they were forked from ISC's source before change #3548.

Resolution

SUSE Linux Enterprise Server 10 SP4 and earlier are affected, though end of life.

All version of SUSE Linux Enterprise Server version that are currently under maintenance and LTSS are not affected by this vulnerability.

Additional Information

Solution:

The vulnerability described in this security advisory was corrected by bug fixes which occurred during the normal course of BIND development and release versions of BIND published by ISC have been safe against this vulnerability since May 2013.

However, versions which were released prior to that date, including some versions which have been used as the basis for installable packages by operating system vendors who maintain their own BIND versions, may be vulnerable.
