CVE-2026-128886Dbus: server accept watch can be stalled by blocking nonce-tcp accept_with_noncefile path

Red Hat Red Hat Enterprise Linux 10 Veröffentlicht: 2026-11-14 00:42 (vor 45 Minuten)

Beschreibung

A flaw was found in dbus when configured with the nonce-tcp transport. An unauthenticated attacker able to connect to an exposed listener can cause a Denial of Service (DoS) by opening a connection and withholding the expected authentication token. Because the server processes this verification without enforcing a timeout, the stalled connection blocks the accept process and prevents legitimate clients from establishing new connections.

Schwachstellentyp (CWE): CWE-1322

Abrt: abrt: abrt-server trusts client-supplied pid= allowing unprivileged read of other processes' /proc environ

Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8

A flaw was found in abrt. abrt-server trusts a client-supplied PID when creating problem dumps over abrt.socket and, running as root, copies that process's /proc data (including environ) into a dump directory owned by the connecting unprivileged user. This al…

A flaw was found in abrt. The completeness check introduced to mitigate CVE-2026-54228 and CVE-2026-54229 only verifies that a dump directory contains a "count" element, which an unprivileged user can create. This allows a local attacker to bypass the guard a…
