Vulnerability Title
Abrt: toctou race condition in abrt-dbus setelement allows arbitrary file writes to dump directories
Source: CVE Program / CVE List V5
Vulnerability Description
A time-of-check time-of-use (TOCTOU) race condition was found in the abrt-dbus D-Bus service's SetElement method. Between dump directory creation and post-create event execution, any local user can call SetElement to write arbitrary text files into the root-owned dump directory, bypassing package validation and allowing crashes of unpackaged binaries to survive post-create processing.

Vulnerability Title
abrt-dbus 竞争条件问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
abrt-dbus是ABRT组织开源的一个提供故障报告数据管理和查询功能的D-Bus后台服务。 abrt-dbus存在竞争条件问题漏洞，该漏洞源于D-Bus服务SetElement方法存在检查时间与使用时间竞争条件。在转储目录创建与post-create事件执行之间的时间窗口内，本地用户可调用SetElement向root权限拥有的转储目录写入任意文本文件，绕过软件包验证机制，导致未打包二进制程序的崩溃转储数据在post-create处理后仍被保留。
