Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU22712

Risk: Low

CVSSv3.1: 4.2 [CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-12207

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local user to perform denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the mechanism responsible for error handling on some Intel platforms. A local user of a guest operating system can use a specially crafted application to trigger memory corruption and cause the host system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated user via the local network (LAN).

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Memory leak

EUVDB-ID: #VU16684

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-20126

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a local attacker to cause DoS condition on the target system.

The vulnerability exists due to memory leakage issue in hw/rdma/vmw/pvrdma_cmd.c when errors are mishandled. A local attacker can create_cq and create_qp memory leaks, resulting in DoS.

Mitigation

Update the affected packages.

Vulnerable software versions

Opensuse: 15.1

http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00034.html


Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) Resource management error

EUVDB-ID: #VU22704

Risk: Low

CVSSv3.1: 5.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2019-11135

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the TSX Asynchronous Abort (TAA) in Intel CPUs. The TAA condition, on some microprocessors utilizing speculative execution, may allow an authenticated user to potentially enable information disclosure via a side channel.

Mitigation

Update the affected packages.

4) Infinite loop

EUVDB-ID: #VU22783

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-12068

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in lsi_execute_script() when reading empty opcode. A local user can consume all available system resources and cause denial of service conditions.

Mitigation

Update the affected packages.

5) Heap-based buffer overflow

EUVDB-ID: #VU20446

Risk: Medium

CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2019-14378

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the ip_reass() function in ip_input.c in libslirp. A remote authenticated attacker can send a large packet, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation
