Description
This security bulletin contains information about 3 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2018-11218)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/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 cause DoS condition on the target system.
The vulnerability exists due to stack-based buffer overflow in the cmsgpack library in the Lua subsystem. A remote unauthenticated attacker can trigger memory corruption and cause the service to crash.
2) Integer overflow (CVE-ID: CVE-2018-11219)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/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 cause DoS condition on the target system.
The vulnerability exists due to integer overflow in the struct library in the Lua subsystem. A remote unauthenticated attacker can trigger memory corruption and cause the service to crash.
3) Buffer overflow (CVE-ID: CVE-2018-12326)
CWE-ID: CWE-120 - Buffer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P/U:Clear
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to a buffer overflow condition in the redis-clicomponent. A local attacker can execute a specially crafted command that submits malicious input, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
