CVE-2026-54229— abrt project ABRT 竞争条件问题漏洞

Abrt: chownproblemdir succeeds during active post-create event processing due to inadequate locking

A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows an attacker to gain filesystem-level control of the dump directory while privileged event scripts are still running.

abrt project ABRT 竞争条件问题漏洞

abrt project abrt是abrt project团队开源的一套自动化故障报告工具。 abrt project ABRT存在竞争条件问题漏洞，该漏洞源于abrt - dbus D - Bus 服务的 ChownProblemDir 方法，ChownProblemDir 以 DD_OPEN_READONLY 打开转储目录，并调用 dd_chown 将所有文件的所有权更改为调用者的 uid，即便 post - create 事件处理程序持有写锁时此操作也能成功，导致攻击者可在特权事件脚本仍在运行时获
