Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU67761

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-2021-29672

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error when processing the current locale settings. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.

Mitigation

Update the affected packages.
app-backup/tsm to version: 8.1.13.3

Vulnerable software versions

Gentoo Linux: All versions

app-backup/tsm: before 8.1.13.3

CPE2.3 External links

https://security.gentoo.org/glsa/202209-02


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) Buffer overflow

EUVDB-ID: #VU56063

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-2021-3711

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 in EVP_PKEY_decrypt() function within implementation of the SM2 decryption. A remote attacker can send specially crafted SM2 content for decryption to trigger a buffer overflow by 62 bytes 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 packages.
app-backup/tsm to version: 8.1.13.3

Vulnerable software versions

Gentoo Linux: All versions

app-backup/tsm: before 8.1.13.3

CPE2.3 External links

https://security.gentoo.org/glsa/202209-02


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) Out-of-bounds read

EUVDB-ID: #VU56064

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-3712

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when processing ASN.1 strings related to a confusion with NULL termination of strings in array. A remote attacker can pass specially crafted data to the application to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.

Mitigation

Update the affected packages.
app-backup/tsm to version: 8.1.13.3

Vulnerable software versions

Gentoo Linux: All versions

app-backup/tsm: before 8.1.13.3

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.

4) Stack-based buffer overflow

EUVDB-ID: #VU67762

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-39048

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error. A local user can trigger a stack-based buffer overflow and crash the application.

Mitigation

Update the affected packages.
app-backup/tsm to version: 8.1.13.3

Vulnerable software versions

Gentoo Linux: All versions

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

5) Deserialization of Untrusted Data

EUVDB-ID: #VU58977

Risk: Medium

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-4104

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

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

The vulnerability exists due to insecure input validation when processing serialized data in JMSAppender, when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution.

Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default.

Mitigation

Update the affected packages.
app-backup/tsm to version: 8.1.13.3
