Description
This security bulletin contains information about 6 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) 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.
3) 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.
4) 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.
5) 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.
6) 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.
