Description
This security bulletin contains information about 6 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2017-4934)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows an adjacent attacker to execute arbitrary code on the target system.
The weakness exists due to a heap-based buffer overflow in the VMNAT device. An adjacent attacker can trigger memory corruption and execute arbitrary code with elevated privileges.
2) Out-of-bounds write (CVE-ID: CVE-2017-4935)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows an adjacent attacker to execute arbitrary code on the target system.
The weakness exists due to out-of-bounds memory write error in JPEG2000 parser in the TPView.dll. An adjacent attacker can trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.
3) Out-of-bounds read (CVE-ID: CVE-2017-4936)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:A/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 an adjacent attacker to cause DoS condtition on the target system.
The weakness exists due to out-of-bounds memory read error in JPEG2000 parser in the TPView.dll. An adjacent attacker can trigger memory corruption and cause the service to crash.
4) Out-of-bounds read (CVE-ID: CVE-2017-4937)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:A/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 an adjacent attacker to cause DoS condtition on the target system.
The weakness exists due to out-of-bounds memory read error in JPEG2000 parser in the TPView.dll. An adjacent attacker can trigger memory corruption and cause the service to crash.
5) Null pointer dereference (CVE-ID: CVE-2017-4938)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:A/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 an adjacent attacker to cause DoS condition on the target system.
The weakness exists due to a guest RPC NULL pointer dereference. An adjacent attacker can cause the application to crash.
6) Insecure DLL loading (CVE-ID: CVE-2017-4939)
CWE-ID: CWE-427 - Uncontrolled Search Path Element
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to insecure .dll loading mechanism when opening files. A local attacker can place a file along with specially crafted .dll file on a remote SBM or WebDAV share and execute arbitrary code on the target system with elevated privileges.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
