Description
This security bulletin contains information about 7 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2018-5125)
CWE-ID: CWE-119 - Memory corruption
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 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.
2) Buffer overflow (CVE-ID: CVE-2018-5127)
CWE-ID: CWE-120 - Buffer overflow
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 weakness exists due to buffer overflow when manipulating the SVg animatedPathSegList through script. 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.
3) Out-of-bounds write (CVE-ID: CVE-2018-5129)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 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/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a lack of parameter validation on IPC messages. A remote attacker can supply specially crafted malformed IPC messages, trigger out-of-bounds write, escape sandbox and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
4) Memory corruption (CVE-ID: CVE-2018-5130)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 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/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a lack of parameter validation on IPC messages. A remote attacker can send packets with a mismatched RTP payload type in WebRTC connections, trigger memory corruption and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
5) Information disclosure (CVE-ID: CVE-2018-5131)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to the fetch() API can return transient local copies of resources that were sent with a no-store or no-cache cache header instead of downloading a copy from the network as it should. A remote attacker can share a common profile while browsing and access previously stored, locally cached data of a website.
6) Integer overflow (CVE-ID: CVE-2018-5144)
CWE-ID: CWE-190 - Integer overflow
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 weakness exists due to integer overflow during conversion of text to some Unicode character sets. A remote attacker can supply unchecked length parameter, trigger overflow and cause the service to crash.
7) Memory corruption (CVE-ID: CVE-2018-5145)
CWE-ID: CWE-119 - Memory corruption
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 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.
