pgAgent scheduled batch job scripts are created in a predictable temporary directory potentially allowing a denial of service

When batch jobs are executed by pgAgent, a script is created in a temporary directory and then executed. In versions of pgAgent prior to 4.2.3, an insufficiently seeded random number generator is used when generating the directory name, leading to the possibility for a local attacker to pre-create the directory and thus prevent pgAgent from executing jobs, disrupting scheduled tasks.

pgAgent 安全漏洞

pgAgent是pgAdmin Project开源的一个 PostgreSQL 的作业调度程序。 pgAgent 4.2.3之前版本存在安全漏洞，该漏洞源于生成目录名时使用的随机数生成器初始化不足，导致本地攻击者可预先创建目录来阻止pgAgent执行作业，从而扰乱计划任务。
