Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Infinite loop
EUVDB-ID: #VU73788
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-2020-14394
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows an attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. A privileged user on the guest OS can consume all available system resources and cause denial of service conditions of the QEMU process on the host.
MitigationUpdate the affected package qemu to the latest version.

2) 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.
