CVE-2026-40209

Опубликовано: 25 июн. 2026
Источник: ubuntu
Приоритет: medium
CVSS3: 5.3

Описание

An attacker might be able to cause outgoing TCP connections to backend to be stuck until a timeout occurs instead of being released immediately, by sending IXFR queries. This could be used to cause a denial of service if there is a limit to the number of concurrent connections to this backend, or if the process runs out of file descriptors.
