Quick assessment

Affected
n/a qemu
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.

QEMU（Quick Emulator）是法国法布里斯-贝拉（Fabrice Bellard）个人开发者的一套模拟处理器软件。该软件具有速度快、跨平台等特点。 Qemu 存在安全漏洞，该漏洞源于virtio_crypto_sym_op_helper() 中不会检查 src_len 和 dst_len 的值，在 virtio_crypto_handle_sym_req() 中处理数据加密或解密请求时可能会发生堆缓冲区溢出。
