Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Use-after-free error (CVE-ID: CVE-2017-5092)
The vulnerability allows a remote attacker to execute arbitrary code.The weakness exists due to use-after free error in PPAPI. A remote attacker can trick the victim into visiting a specially crafted web page, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
2) Spoofing attack (CVE-ID: CVE-2017-5093)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to UI spoofing in Blink. A remote attacker can create a specially crafted web page, trick the victim into visiting it and conduct domain spoofing attacks.
Successful exploitation of the vulnerability results in address spoofing.
3) Out-of-bounds write (CVE-ID: CVE-2017-5095)
The vulnerability allows a remote attacker to execute arbitrary code.The weakness exists due to out-of-bounds write in PDFium. A remote attacker can trick the victim into visiting a specially crafted web page and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
4) Out-of-bounds read (CVE-ID: CVE-2017-5097)
The vulnerability allows a remote attacker to obtain potentially sensitive information on the system.The weakness exists due to out-of-bounds read in Skia. A remote attacker can trick the victim into visiting a specially crafted web page and read important files on the system.
