Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2019-11745)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the NSC_EncryptUpdate() function in /lib/softoken/pkcs11c.c, when performing padding operations in Mozilla NSS. A remote attacker can pass specially crafted data to the affected application, trigger out-of-bounds write and execute arbitrary code on the target system.
2) Stack-based buffer overflow (CVE-ID: CVE-2019-13722)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing number of arguments during setting a thread name on Windows in WebRTC. A remote unauthenticated attacker can create a specially crafted web page, trick the victim into visiting it, trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Buffer overflow (CVE-ID: CVE-2019-17005)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a memory corruption in plain text serializer. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a buffer overflow and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
4) Use-after-free (CVE-ID: CVE-2019-17008)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error during worker destruction. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a use-after-free error and crash the application or execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
5) Incorrect default permissions (CVE-ID: CVE-2019-17009)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect default permissions for status and log files files that are set by the updater service. A local user with access to the system can view contents of files and gain access to sensitive information.
6) Use-after-free (CVE-ID: CVE-2019-17010)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when checking the Resist Fingerprinting preference during device orientation checks. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a race condition that will results in a use-after-free error.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
7) Use-after-free (CVE-ID: CVE-2019-17011)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when retrieving a document from a DocShell in the antitracking code. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a race condition that will results in a use-after-free error.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
8) Buffer overflow (CVE-ID: CVE-2019-17012)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a memory corruption when processing HTML content. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a buffer overflow and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
