Description
This security bulletin contains information about 3 vulnerabilities.
1) Resource management error (CVE-ID: CVE-2025-21605)
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 output buffers. A remote attacker can cause the output buffer to grow from "NOAUTH" responses until the system will run out of memory.
2) 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.
3) Integer underflow (CVE-ID: CVE-2025-49112)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to an integer underflow within the setDeferredReply() function in networking.c. A remote attacker can send a specially crafted request to the affected application, trigger an integer underflow and perform a denial of service attack.
