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… Yayım: (5 ay önce)

Açıklama

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.

Zayıflık türü (CWE): CWE-59

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.
