An update for rsyslog is now available for openEuler-24.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-3840 Final 1.0 1.0 2026-09-14 Initial 2026-09-14 2026-09-14 openEuler SA Tool V1.0 2026-09-14 rsyslog security update An update for rsyslog is now available for openEuler-24.03-LTS-SP1 RSYSLOG is the rocket-fast system for log processing.It offers high-performance, great security features and a modular design. While it started as a regular syslogd, rsyslog has evolved into a kind of swiss army knife of logging, being able to accept inputs from a wide variety of sources, transform them, and output to the results to diverse destinations. Security Fix(es): Rsyslog is an open-source log processing system. The replace() function in the RainerScript scripting language has a heap buffer overflow vulnerability due to incorrect calculation of buffer size (CWE-131), leading to a heap-based buffer overflow (CWE-122). An attacker could exploit this vulnerability to cause denial of service or potential code execution.(CVE-2026-78002) An update for rsyslog is now available for openEuler-24.03-LTS-SP1. openEuler Security has rated this update as having a security impact of high.
