Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
EUVDB-ID: #VU31805
Risk: Medium
CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-10761
CWE-ID:
CWE-617 - Reachable Assertion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion in the Network Block Device(NBD) Server. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service.
MitigationUpdate the affected packages.
Opensuse: 15.2

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU31801
Risk: Medium
CVSSv3.1: 8.2 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-13361
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing frame count in es1370_transfer_audio in hw/audio/es1370.c. A local user on the guest operating system can send a specially crafted request and execute arbitrary code on the host operating system.
Update the affected packages.

EUVDB-ID: #VU31802
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-13362
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in megasas_lookup_frame in hw/scsi/megasas.c. A local user on the guest operating system can pass specially crafted message with reply_queue_head field, trigger out-of-bounds read error and read contents of memory on the system.
MitigationUpdate the affected packages.

CVE-ID: CVE-2020-13659
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in ati-vga in hw/display/ati.c. A local user on the guest operating system can trigger infinite recursion via a crafted mm_index value during an ati_mm_read or ati_mm_write call and perform a denial of service attack against the host system.
MitigationUpdate the affected packages.
