CVE-2026-110330Abrt: 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 Publicada: 2026-11-14 00:26 (hace 1 hora)

Descripción

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 allows a local attacker to read environment variables and related metadata of other users' or root processes when abrtd is running.

Debilidad (CWE): CWE-862

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…
