Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU18061
Risk: High
CVSSv4.0: 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/E:A/U:Amber]
CVE-ID: CVE-2019-9810
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing incorrect information alias in IonMonkey JIT compiler for Array.prototype.slice method. A remote attacker can create a specially crafted web page, trick the victim into visiting 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.

2) Type Confusion
EUVDB-ID: #VU18062
Risk: High
CVSSv4.0: 7.3 [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:P/U:Amber]
CVE-ID: CVE-2019-9813
CWE-ID:
CWE-843 - Type confusion
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error when handling proto mutations in IonMonkey JIT code. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a type confusion error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
