Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU29016

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-12723

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) áttack.

The vulnerability exists due to a boundary error within the recursive "S_study_chunk" calls. A remote attacker can use a specially crafted regular expression , trigger memory corruption and cause a denial of service condition on the target system.

Mitigation

Install update from vendor's website.

Vulnerable software versions

IBM Watson Assistant for IBM Cloud Pak for Data: 4.0.2 - 4.6.3

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.

2) Integer overflow

EUVDB-ID: #VU29014

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-2020-10543

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to integer overflow in nested regular expression quantifiers. A remote attacker can pass specially crafted data to the application, trigger integer overflow, leading to heap-based buffer overflow 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.

3) Integer overflow

EUVDB-ID: #VU29015

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-2020-10878

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A remote attacker can use a specially crafted regular expression, trigger integer overflow 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.
