Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Incorrect Conversion between Numeric Types

EUVDB-ID: #VU51455

Risk: Low

CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-27218

CWE-ID: CWE-681 - Incorrect Conversion between Numeric Types

Exploit availability: No

Description

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to incorrect conversion between numeric types in Gnome Glib. If g_byte_array_new_take() was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2**32, causing unintended length truncation.

Mitigation

Install update from vendor's website.

2) Integer overflow

EUVDB-ID: #VU51456

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-2021-27219

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to integer overflow within the g_bytes_new() function on 64-bit platforms due to an implicit cast from 64 bits to 32 bits. A local user can run a specially crafted program to trigger an integer overflow and execute arbitrary code with elevated privileges.

Mitigation

Install update from vendor's website.
