Quick assessment

Affected
NationalSecurityAgency ghidra
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action

Ghidra 12.2 之前的版本中存在一个漏洞：ExtensionUtils.unzipToInstallationFolder() 函数对高压缩数据的处理不当，攻击者可借此耗尽磁盘空间。攻击者可以诱使用户安装经过恶意构造的"zip 炸弹”扩展程序归档包，该归档包在解压时会无限制地膨胀，导致 Ghidra 及其他后续写入操作失败。
