Type:
security
Severity:
Important
Release date:
2026-09-01 11:39:02 UTC
Description:
* SECURITY UPDATE: denial of service in the optional imptcp module: a regex match at offset zero after oversize-frame recovery submits a negative message length and crashes rsyslogd - debian/patches/CVE-2026-19654.patch: denial of service in the optional imptcp module: a regex match at offset zero after oversize-frame recovery submits a negative message length and crashes rsyslogd - CVE-2026-19654 * debian/patches/Skip-tests-that-cannot-run-in-the-build-environment.patch: skip omfile-read-only, omfile-read-only-errmsg, privdropuser and privdropuserid. All four fail in the pdebuild chroot for reasons unrelated to rsyslog (root bypasses the 0400 mode the first two rely on; the chroot has no unprivileged test user for the last two), and they fail identically on the unpatched vendor sources.
