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

Libgcrypt是GNU计划开发的一个基于GnuPG代码的通用加密库。该库实现了各种加密算法，包括对称密码、哈希算法、公开密钥算法等。 Libgcrypt 1.6.5之前版本中存在安全漏洞，该漏洞源于程序在解密期间没有正确执行elliptic-point曲线乘法。物理位置临近的攻击者可通过测量电磁辐射利用该漏洞提取ECDH密钥。
