Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU64569
Risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-3507
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the fdctrl_transfer_handler() function in hw/block/fdc.c while processing DMA read
data transfers from the floppy drive to the guest system. A remote privileged user on the guest OS can trigger a heap-based buffer overflow and crash the QEMU process on the host OS.
Update the affected package qemu to the latest version.
