Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Memory corruption

EUVDB-ID: #VU27

Risk: High

CVSSv3.1: 8.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]

CVE-ID: CVE-2016-4997

CWE-ID: CWE-119 - Memory corruption

Exploit availability: Yes

Description

The vulnerability allows a local user to obtain elevated privileges on the target system.

The vulnerability exists due to a memory corruption error in the IPT_SO_SET_REPLACE compat_setsockopt() function.

Successful exploitation of this vulnerability may lead to arbitrary code execution with kernel-level privileges.

Mitigation

Update the affected packages.

Vulnerable software versions

Oracle Linux: 5 - 7

Oracle VM Server for x86: 3.2

CPE2.3 External links

http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00053.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. However, a fully functional exploit for this vulnerability is available.

2) Heap-based buffer overflow

EUVDB-ID: #VU4080

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-5829

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

Exploit availability: No

Description

The vulnerability allows a local attacker to cause DoS condition or gain elevated privileges on the target system.

The weakness exists in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c  due to heap-based buffer overflow. A local attacker can cause the service to crash or gain elevated privileges via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call.

Mitigation

Update the affected packages.

Vulnerable software versions

Linux kernel: 4.6.0 - 4.6.2

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) Race condition

EUVDB-ID: #VU359

Risk: Medium

CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-6480

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows local users to provoke a denial of service.

The vulnerability exists due to parafunction of ioctl_send_fib. By altering "double fetch" vulnerability, a local user can provoke a denial of service.

Successful exploitation of this vulnerability will allow an attacker to cause a denial of service

Mitigation

Update the affected packages.

Vulnerable software versions

Oracle VM Server for x86: 3.2 - 3.4
