Summary
rsyslog security update
Details

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)
