Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Integer overflow
EUVDB-ID: #VU57031
Risk: Medium
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-32687
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 when handling intsets, if set-max-intset-entries is manually configured to a non-default, very large value. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

2) Integer overflow
EUVDB-ID: #VU57032
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-32628
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 when handling ziplist-encoded data types, when configuring a large, non-default value for hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries or zset-max-ziplist-value.

3) Integer overflow
EUVDB-ID: #VU57029
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-2021-41099
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 when handling untrusted input, if proto-max-bulk-len is manually configured to a non-default, very large value. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Input validation error
EUVDB-ID: #VU57034
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-2021-32675
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when processing RESP request payloads with a large number of elements on many connections. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-32762
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 when handling large multi-bulk replies on some older and less common platforms in redis-cli and redis-sentinel. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
