2) Out-of-bounds read

EUVDB-ID: #VU67970

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-42011

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error caused by an invalid array of fixed-length elements where the length of the array is not a multiple of the length of the element. A local user can trigger an out-of-bounds read and gain access to sensitive information.

Mitigation

Update the affected package dbus-1 to the latest version.

3) Use-after-free

EUVDB-ID: #VU67971

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-2022-42012

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error caused by a message in non-native endianness with out-of-band Unix file descriptors. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package dbus-1 to the latest version.
