Quick assessment

Affected
xerial snappy-java
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.

Xerial snappy-java 从 1.1.7.4 到 1.1.10.10（不含 1.1.10.10）版本在 SnappyFramedInputStream 中存在一个双重释放漏洞。当替换分配失败时，该漏洞会导致池化缓冲区被释放两次。攻击者可以构造具有超大声明块长度的帧数据，从而触发内存溢出错误（OutOfMemoryError），导致共享底层数组暴露或覆盖其他流的解压缩数据。
