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.
Dislocker 0.7.3 及之前版本在 和 函数中存在堆越界读取漏洞，这两个函数未对 dataset 和 datum 的大小与元数据分配大小进行验证。攻击者可以构造具有夸大 dataset 或 datum 大小的 BitLocker 卷镜像，当该卷镜像被打开或挂载时，可导致 dislocker 崩溃或泄露相邻堆内存。
