CVE-2017-9445 (GCVE-0-2017-9445)

Vulnerability from cvelistv5 – Published: 2017-06-28 06:00 – Updated: 2024-08-05 17:11

Summary

In systemd through 233, certain sizes passed to dns_packet_new in systemd-resolved can cause it to allocate a buffer that's too small. A malicious DNS server can exploit this via a response with a specially crafted TCP payload to trick systemd-resolved into allocating a buffer that's too small, and subsequently write arbitrary data beyond the end of it.

Severity

No CVSS data available.
