Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Improper Verification of Cryptographic Signature

EUVDB-ID: #VU59993

Risk: Medium

CVSSv4.0: 6.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-3521

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to an error in RPM's signature functionality, as RPM does not check the binding signature of subkeys before importing them. A remote attacker with ability to add malicious subkey to a legitimate public key can run malicious code on the system.


Mitigation

Install update from vendor's website.

Vulnerable software versions

IBM Supplied MQ Advanced Queue Manager Container images: before 9.2.0.5-r1-eus

IBM MQ Operator: before 1.3.3

https://bugzilla.redhat.com/show_bug.cgi?id=1941098


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

2) Off-by-one

EUVDB-ID: #VU61293

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

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

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

3) LDAP injection

EUVDB-ID: #VU59970

Risk: Medium

CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-39031

CWE-ID: CWE-90 - Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')

Exploit availability: No

Description

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

The vulnerability exists due to improper input validation when processing DLAP queries. A remote user can send a specially crafted request to modify the original LDAP query and gain unauthorized access to the application.

Mitigation

Install update from vendor's website.

4) Buffer overflow

EUVDB-ID: #VU61295

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2022-23219

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 clnt_create() function in the sunrpc module. 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

Install update from vendor's website.
