Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2018-11218)
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)
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)
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.
4) Heap-based buffer overflow (CVE-ID: CVE-2019-10192)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing Redis hyperloglog data structure. A remote attacker can carefully corrupt hyperloglog using the SETRANGE command, 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.
