Title:	Debian: Security Advisory (DLA-3016-1)
Summary:	The remote host is missing an update for the Debian 'rsyslog' package(s) announced via the DLA-3016-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'rsyslog' package(s) announced via the DLA-3016-1 advisory. Vulnerability Insight: Several vulnerabilities were discovered in rsyslog, a system and kernel logging daemon. When a log server is configured to accept logs from remote clients through specific modules such as imptcp, an attacker can cause a denial of service (DoS) and possibly execute code on the server. CVE-2018-16881 A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a specially crafted message to the imptcp socket, which would cause rsyslog to crash. CVE-2022-24903 Modules for TCP syslog reception have a potential heap buffer overflow when octet-counted framing is used. This can result in a segfault or some other malfunction. For Debian 9 stretch, these problems have been fixed in version 8.24.0-1+deb9u2. We recommend that you upgrade your rsyslog packages. For the detailed security status of rsyslog please refer to its security tracker page at: [link moved to references] Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references] Affected Software/OS: 'rsyslog' package(s) on Debian 9.
