Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 SQLite 3.54.0 之前的版本中，函数存在栈耗尽漏洞。攻击者可通过在大型多行 VALUES 子句中使用，触发深度嵌套的表达式；这些表达式在函数中进行递归释放时，会耗尽 C 语言调用栈，从而导致宿主进程崩溃，引发拒绝服务（DoS）攻击。攻击者只需提供恶意构造的 SQL 语句或包含特制视图的数据库文件即可触发该漏洞。

Vulnerability Title

SQLite before 3.54.0 Stack Exhaustion via countOfViewOptimization() in VALUES Clause

Source: CVE Program / CVE List V5

Vulnerability Description

SQLite before 3.54.0 contains a stack exhaustion vulnerability in countOfViewOptimization() that allows attackers to crash the host process via count(*) over a large multi-row VALUES clause. Attackers supplying SQL or a database file with a crafted view can trigger deeply nested TK_PLUS expressions whose recursive freeing in sqlite3ExprDeleteNN() exhausts the C stack, causing denial of service.
