Description

This security bulletin contains information about 2 vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2018-6981)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 7.1 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows an adjacent attacker to execute arbitrary code on the target system.

The weakness exists due to uninitialized stack memory usage in the vmxnet3 virtual network adapter. A remote attacker can trigger memory corruption if vmxnet3 is enabled and execute arbitrary code with elevated privileges.


2) Stack-based buffer overflow (CVE-ID: CVE-2018-6982)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 5.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows an adjacent attacker to obtain potentially sensitive information on the target system.

The weakness exists due to uninitialized stack memory usage in the vmxnet3 virtual network adapter. A remote attacker can trigger memory corruption if vmxnet3 is enabled and access arbitrary data.
