Source: rsyslog Version: 8.2606.0-4 Severity: important Tags: security upstream Forwarded: https://github.com/rsyslog/rsyslog/pull/7410 X-Debbugs-Cc: [email protected], Debian Security Team <[email protected]> Hi, The following vulnerability was published for rsyslog. CVE-2026-19654[0]: | A unauthenticated remote peer may lead rsyslogd to crash due to a | flaw in the optional imptcp module. A crafted input sequence during | oversize-frame recovery can cause an invalid internal message length | and terminate rsyslogd. No confidentiality or integrity impact, | privilege escalation, or code execution has been identified. imtcp | and the default imptcp framing modes are not affected. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry. For further information see: [0] https://security-tracker.debian.org/tracker/CVE-2026-19654 https://www.cve.org/CVERecord?id=CVE-2026-19654 [1] https://github.com/rsyslog/rsyslog/security/advisories/GHSA-cj5r-wh2m-7w29 [2] https://github.com/rsyslog/rsyslog/pull/7410 [3] https://www.openwall.com/lists/oss-security/2026/07/22/5 Please adjust the affected versions in the BTS as needed.
According to https://github.com/rsyslog/rsyslog/security/advisories/GHSA-cj5r-wh2m-7w29 it is 8.36.0+, so marking accordingly.
The CVSS metric for this bug says 7.5/10, which I suppose is mostly due to the network attack vector.
Given the module is not enabled by default and I would suspect it's not that widely used, I would say a security upload is not necessary and I would just make a stable upload for rsyslog.
What's your take? Regards, Michael
