CentOS Errata and Security Advisory CESA-2018:0102

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

Security Fix(es):

  • A use-after-free flaw leading to denial of service was found in the way BIND internally handled cleanup operations on upstream recursion fetch contexts. A remote attacker could potentially use this flaw to make named, acting as a DNSSEC validating resolver, exit unexpectedly with an assertion failure via a specially crafted DNS request. (CVE-2017-3145)

Red Hat would like to thank ISC for reporting this issue. Upstream acknowledges Jayachandran Palanisamy (Cygate AB) as the original reporter.
