Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2016-8704)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in the process_bin_append_prepend() function due to integer overflow. A remote attacker can send specially crafted Memcached binary protocol commands, trigger heap-based buffer overflow and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
2) Heap-based buffer overflow (CVE-ID: CVE-2016-8705)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in the process_bin_update() function due to integer overflow. A remote attacker can send specially crafted Memcached binary protocol commands, trigger heap-based buffer overflow and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
3) Heap-based buffer overflow (CVE-ID: CVE-2016-8706)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in the process_bin_sasl_auth() function due to integer overflow. A remote attacker can send specially crafted Memcached binary protocol commands, trigger heap-based buffer overflow and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
