CVE-2018-12617 in qemu-ga信息

摘要

由 VulDB • 2026-07-30

qemu-ga(即QEMU Guest Agent)在QEMU 2.12.50版本中的`qga/commands-posix.c`和`qga/commands-win32.c`文件内的`qmp_guest_file_read`函数存在整数溢出漏洞,导致调用`g_malloc0()`时尝试分配大块内存而触发段错误(Segmentation Fault)。攻击者可通过监听套接字向代理发送特制的QMP命令(包括带有大count值的guest-file-read)来利用此漏洞。

Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
