Description
This security bulletin contains information about 6 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2017-7771)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.9 [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]
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)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
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)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.9 [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]
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)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.9 [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]
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.
