Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Infinite loop
EUVDB-ID: #VU33055
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-6505
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a local authenticated user to a crash the entire system.
The ohci_service_ed_list function in hw/usb/hcd-ohci.c in QEMU (aka Quick Emulator) before 2.9.0 allows local guest OS users to cause a denial of service (infinite loop) via vectors involving the number of link endpoint list descriptors, a different vulnerability than CVE-2017-9330.
MitigationUpdate the affected packages.

No. We are not aware of malware exploiting this vulnerability.
2) Out-of-bounds read
EUVDB-ID: #VU31985
Risk: Low
CVSSv3.1: 3.7 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-7228
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. The earlier XSA-29 fix introduced an insufficient check on XENMEM_exchange input, allowing the caller to drive hypervisor memory accesses outside of the guest provided input/output arrays.
MitigationUpdate the affected packages.
