Vulnerability Title
Abrt: chownproblemdir succeeds during active post-create event processing due to inadequate locking
Source: CVE Program / CVE List V5
Vulnerability Description
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.
