CVE-2026-54230Abrt: event handler scripts follow symlinks when writing output files, allowing arbitrary file overwrites

Red Hat Red Hat Enterprise Linux 7 Extended Lifecycle Support; Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 8.4 Advanced Mission Critic… Publicada: (hace 5 meses)

Descripción

A symlink following vulnerability was found in the ABRT post-create event handler scripts in libreport. Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and writes content to the symlink target, allowing arbitrary file overwrites on the system.

Debilidad (CWE): CWE-59
