NVD Description

Note: Versions mentioned in the description apply to the upstream glibc package. See Remediation section below for Ubuntu:16.04 relevant versions.

Memory leak in the __res_vinit function in the IPv6 name server management code in libresolv in GNU C Library (aka glibc or libc6) before 2.24 allows remote attackers to cause a denial of service (memory consumption) by leveraging partial initialization of internal resolver data structures.

Remediation

Upgrade Ubuntu:16.04 glibc to version 2.23-0ubuntu6 or higher.
