Summary
Important: rsyslog security update
Details

The rsyslog packages provide an enhanced, multi-threaded syslog daemon. It supports MySQL, syslog/TCP, RFC 3195, permitted sender lists, filtering on any message part, and fine-grained control over output format.

Security Fix(es):

  • rsyslog: A configuration-dependent issue in rsyslog's optional imptcp input module can allow an unauthenticated remote peer to crash rsyslogd (CVE-2026-19654)
  • rsyslog: rsyslog: Denial of service via heap buffer overflow in RainerScript replace() function (CVE-2026-78002)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
