Description
This security bulletin contains information about 6 vulnerabilities.
1) Untruster pointer dereference (CVE-ID: CVE-2018-17893)
CWE-ID: CWE-822 - Untrusted Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to untrusted pointer dereference. A remote unauthenticated attacker can trigger untrusted pointer dereference and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Out-of-bounds read (CVE-ID: CVE-2018-17895)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to out-of-bounds read. A remote unauthenticated attacker can trigger out-of-bounds read and cause the service to crash.
3) Integer overflow (CVE-ID: CVE-2018-17897)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow. A remote unauthenticated attacker can trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Path traversal (CVE-ID: CVE-2018-17899)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to conduct directory traversal on the target system.
The vulnerability exists due to path traversal. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, conduct directory traversal attack and execute arbitrary code.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Out-of-bounds write (CVE-ID: CVE-2018-17901)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to out-of-bounds write when processing project files. A remote unauthenticated attacker can trick the victim into opening a specially crafted input, perform write operations on a stack object and execute code under the current process.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Stack-based buffer overflow (CVE-ID: CVE-2018-17911)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to stack-based buffer overflow. A remote unauthenticated attacker can trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
