CVE-2018-12617 (GCVE-0-2018-12617)

Vulnerability from cvelistv5 – Published: 2018-06-21 18:00 – Updated: 2024-08-05 08:38

Summary

qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.

Severity

7.5 (High)
