Description

This security bulletin contains information about 1 vulnerability.


1) Race condition (CVE-ID: CVE-2019-12448)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to overwrite or access sensitive information, or cause a denial of service (DoS) condition on a targeted system.

The vulnerability exists due to race conditions in the daemon/gvfsbackendadmin.c source code file because the admin backend does not implement the query_info_on_read/write functionality. A remote attacker can send a request with malicious input to the system and cause race condition that will allow to overwrite or access sensitive information or cause a DoS condition.
