Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2020-10531)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow in UnicodeString::doAppend() function in common/unistr.cpp. A remote attacker can pass specially crafted string to the application that is using the vulnerable library, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Resource exhaustion (CVE-ID: CVE-2020-11080)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when processing HTTP/2 SETTINGS frames. A remote attacker can trigger high CPU load by sending large HTTP/2 SETTINGS frames and perform a denial of service (DoS) attack.


3) Improper Authorization (CVE-ID: CVE-2020-8172)

The vulnerability allows a remote attacker to bypass authorization process.

The vulnerability exists due to TLS session reuse and host certificate verification bypass, as the 'session' event can be emitted before the 'secureConnect' event in Node.js. The application agent performs https session caching and an unauthorized connection can be established via the cached session ticket and treated as authorized connection.


4) Buffer overflow (CVE-ID: CVE-2020-8174)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() functions. A remote attacker can create a specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
