glibc: CVE-2017-12132

Severity: Medium · CVSS 5.9CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N
Published: Apr 7, 2017, 12:00:00 AM UTC

EPSS: 1.96% · Oct 25, 2026

The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation.
