Description
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2025-32023)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a boundary error on hyperloglog operations. A remote user can trigger an out-of-bounds write and execute arbitrary code on the target system.
2) Resource management error (CVE-ID: CVE-2025-48367)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when handling connection errors. A remote non-authenticated attacker can cause repeated IP protocol errors leading to client starvation and a denial of service condition.
3) Stack-based buffer overflow (CVE-ID: CVE-2025-27151)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing file names. A remote attacker can trick the victim into passing an overly long file path to the redis-check-aof cli, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
