Amazon Linux 1 (EOL) Security Advisory: ALAS-2018-954
Advisory Released Date: 2018-02-20
Advisory Updated Date: 2018-02-21
Severity:
Important
Issue Overview:
Improper fetch cleanup sequencing in the resolver can cause named to crash:
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)
Affected Packages:
bind
Issue Correction:
