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
DescriptionThe 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.
MitigationInstall update from vendor's website.
Vulnerable software versionsIBM 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
DescriptionThe 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.

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
DescriptionThe 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.
