Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU28397

Risk: Low

CVSSv3.1: 4.9 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-12126

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

Microarchitectural Store Buffer Data Sampling (MSBDS): Store buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. A list of impacted products can be found here: https://www.intel.com/content/dam/www/public/us/en/documents/corporate-information/SA00233-microcode-update-guidance_05132019.pdf

Mitigation

Update the affected packages.

4) Buffer overflow

EUVDB-ID: #VU19189

Risk: Medium

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-20815

CWE-ID: CWE-119 - Memory corruption

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 in the deprecated "load_image" function, as defined in the "device_tree.c" file. A remote attacker can submit a large image file to the affected system, trigger memory corruption and execute arbitrary code on the target system.

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

Mitigation

Update the affected packages.
