Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Incorrect Conversion between Numeric Types

EUVDB-ID: #VU51455

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

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

Update the affected package glib2 to the latest version.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Integer overflow

EUVDB-ID: #VU51456

Risk: Low

CVSSv4.0: 5.9 [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]

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

Update the affected package glib2 to the latest version.
