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 3.54.0 之前的 SQLite 版本中存在一个栈耗尽漏洞。攻击者可以通过链式使用 COLLATE 后缀运算符来绕过 SQLITE_LIMIT_EXPR_DEPTH 限制。攻击者可以在 SQL 语句或不可信的数据库视图中提供大约 175,000 个链式连接的 COLLATE 运算符，从而触发 sqlite3WalkExprNN() 函数中的无界递归，导致进程崩溃。

Vulnerability Title

SQLite before 3.54.0 Stack Exhaustion via COLLATE Operator Chain

Source: CVE Program / CVE List V5

Vulnerability Description

SQLite before 3.54.0 contains a stack exhaustion vulnerability that allows attackers to bypass the SQLITE_LIMIT_EXPR_DEPTH limit by chaining COLLATE postfix operators. Attackers can supply roughly 175,000 chained COLLATE operators in SQL or an untrusted database view to trigger unbounded recursion in sqlite3WalkExprNN() and crash the process.
