Description
This security bulletin contains information about 6 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2017-7771)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in Graphite 2 library due to out-of-bounds-read. A remote attacker can cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
2) Heap-buffer-overflow write (CVE-ID: CVE-2017-7772)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in Graphite 2 library due to heap-buffer-overflow write. A remote attacker can execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
3) Denial of service (CVE-ID: CVE-2017-7777)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in Graphite 2 library due to use of uninitialized memory. A remote attacker can cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
4) Heap-buffer-overflow read (CVE-ID: CVE-2017-7776)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in Graphite 2 library due to heap-buffer-overflow read. A remote attacker can cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
5) Out-of-bounds read (CVE-ID: CVE-2017-7774)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in Graphite 2 library due to out-of-bounds-read. A remote attacker can cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
6) Heap-buffer-overflow write (CVE-ID: CVE-2017-7773)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in Graphite 2 library due to heap-buffer-overflow write. A remote attacker can execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
