Description

This security bulletin contains information about 7 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2018-0746)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to obtain potentially sensitive information.

The vulnerability exists due to an error which can lead to ASLR bypass . A local user can retrieve the memory address of a kernel object and bypass ASLR protection mechanism.

2) Information disclosure (CVE-ID: CVE-2018-0747)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to obtain potentially sensitive information.

The vulnerability exists due to an error which can lead to ASLR bypass . A local user can retrieve the memory address of a kernel object and bypass ASLR protection mechanism.

3) Privilege escalation (CVE-ID: CVE-2018-0748)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way Windows Kernel API enforces permissions. A local user can use a specially crafted application to impersonate processes, interject cross-process communication, or interrupt system functionality.

4) Privilege escalation (CVE-ID: CVE-2018-0751)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way Windows Kernel API enforces permissions. A local user can use a specially crafted application to impersonate processes, interject cross-process communication, or interrupt system functionality.

5) Privilege escalation (CVE-ID: CVE-2018-0752)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way Windows Kernel API enforces permissions. A local user can use a specially crafted application to impersonate processes, interject cross-process communication, or interrupt system functionality.

6) Memory corruption (CVE-ID: CVE-2018-0744)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in Windows kernel. A local user can use a specially crafted application to trigger memory corruption and execute arbitrary code on the target system with SYSTEM privileges.


7) Information disclosure (CVE-ID: CVE-2018-0745)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to obtain potentially sensitive information.

The vulnerability exists due to an error which can lead to ASLR bypass . A local user can retrieve the memory address of a kernel object and bypass ASLR protection mechanism.
