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.\r\n\r\nSecurity Fix(es):\n\nRsyslog 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)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"rsyslog","purl":"pkg:rpm/openEuler/rsyslog&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.2210.0-12.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["rsyslog-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-crypto-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-debuginfo-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-debugsource-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-elasticsearch-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-gnutls-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-gssapi-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-hiredis-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-kafka-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-mmaudit-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-mmjsonparse-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-mmkubernetes-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-mmnormalize-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-mmsnmptrapd-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-mongodb-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-mysql-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-omamqp1-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-pgsql-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-rabbitmq-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-relp-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-snmp-8.2210.0-12.oe2203sp4.aarch64.rpm","rsyslog-udpspoof-8.2210.0-12.oe2203sp4.aarch64.rpm"],"noarch":["rsyslog-help-8.2210.0-12.oe2203sp4.noarch.rpm"],"src":["rsyslog-8.2210.0-12.oe2203sp4.src.rpm"],"x86_64":["rsyslog-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-crypto-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-debuginfo-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-debugsource-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-elasticsearch-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-gnutls-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-gssapi-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-hiredis-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-kafka-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-mmaudit-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-mmjsonparse-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-mmkubernetes-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-mmnormalize-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-mmsnmptrapd-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-mongodb-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-mysql-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-omamqp1-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-pgsql-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-rabbitmq-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-relp-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-snmp-8.2210.0-12.oe2203sp4.x86_64.rpm","rsyslog-udpspoof-8.2210.0-12.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3839"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-78002"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}],"database_specific":{"severity":"High"}}
