Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Data Handling

EUVDB-ID: #VU31436

Risk: Medium

CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-8985

CWE-ID: CWE-19 - Data Handling

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The pop_fail_stack function in the GNU C Library (aka glibc or libc6) allows context-dependent attackers to cause a denial of service (assertion failure and application crash) via vectors related to extended regular expression processing.

Mitigation

Update the affected package glibc to the latest version.

2) Off-by-one

EUVDB-ID: #VU61293

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-3999

CWE-ID: CWE-193 - Off-by-one Error

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the system.

The vulnerability exists due to an off-by-one error glibc getcwd() function. A remote attacker can pass specially crafted input to the application that is using the affected library version, trigger an off-by-one error and execute arbitrary code on the target system.

Mitigation

Update the affected package glibc to the latest version.

3) Buffer overflow

EUVDB-ID: #VU61294

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-23218

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the svcunix_create() in the sunrpc module ib glibc. A remote attacker can pass specially crafted input to the application that is using the affected library version, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package glibc to the latest version.
