An update for c-ares is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1312 Final 1.0 1.0 2023-06-03 Initial 2023-06-03 2023-06-03 openEuler SA Tool V1.0 2023-06-03 c-ares security update An update for c-ares is now available for openEuler-22.03-LTS. This is c-ares, an asynchronous resolver library. It is intended for applications which need to perform DNS queries without blocking, or need to perform multiple Security Fix(es): c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful shutdown of the connection. This issue has been patched in version 1.19.1.(CVE-2023-32067) An update for c-ares is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high.
