CVE-2026-110331Abrt: abrt: incomplete cve-2026-54228/54229 fix — completeness gate bypassed via attacker-supplied count element

Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8 Publicada: 2026-11-14 00:25 (hace 1 hora)

Descripción

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 and again poison elements in, or seize ownership of, dump directories while privileged ABRT handlers are processing them. Related Problems2 mutating methods remain ungated by the same check.

Debilidad (CWE): CWE-862
