Description
This security bulletin contains information about 5 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2017-7810)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 8.6 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper bounds checking. A remote attacker can create a specially crafted web page, trick the victim into opening it and execute arbitrary code on the target system.
2) Buffer overflow (CVE-ID: CVE-2017-7826)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 8.6 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to unspecified boundary errors when processing web pages. A remote unauthenticated attacker can create a specially crafted web page, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Memory corruption (CVE-ID: CVE-2018-5089)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 8.6 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger mmeory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
4) Memory corruption (CVE-ID: CVE-2018-5125)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 8.6 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
5) Buffer overflow (CVE-ID: CVE-2018-5150)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 8.6 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability result may result in system compromise.
