Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2021-32626)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing specially crafted Lua scripts. A remote attacker can pass specially crafted data to the application, trigger 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.
2) Integer overflow (CVE-ID: CVE-2021-32627)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow when handling streams, if configuring a non-default, large value for proto-max-bulk-len and client-query-buffer-limit. 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.
3) Integer overflow (CVE-ID: CVE-2021-32628)
The 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. 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 (CVE-ID: CVE-2021-32675)
The 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.
5) Integer overflow (CVE-ID: CVE-2021-32687)
The 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.
6) Integer overflow (CVE-ID: CVE-2021-32762)
The 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.
7) Integer overflow (CVE-ID: CVE-2021-41099)
The 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.
8) Code Injection (CVE-ID: CVE-2022-24735)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation in the Lua script execution environment. A remote user can send a specially crafted request and execute arbitrary code on the target system with elevated privileges.
9) NULL pointer dereference (CVE-ID: CVE-2022-24736)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can use a specially crafted Lua script and perform a denial of service (DoS) attack.
10) Integer overflow (CVE-ID: CVE-2022-35977)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in SETRANGE and SORT/SORT_RO commands. A remote attacker can pass specially crafted input to the application, trigger an integer overflow and perform a denial of service (DoS) attack.
11) Integer overflow (CVE-ID: CVE-2023-25155)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in the "SRANDMEMBER", "ZRANDMEMBER" and "HRANDFIELD" commands. A local user can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
12) Use-after-free (CVE-ID: CVE-2024-46981)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when handling Lua script commands. A remote user can pass a specially crafted Lua script to the application and execute arbitrary code on the system..
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
