Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2020-7015)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can permanently inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
2) Infinite loop (CVE-ID: CVE-2020-14040)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The x/text package before 0.3.3 for Go has a vulnerability in encoding/unicode that could lead to the UTF-16 decoder entering an infinite loop, causing the program to crash or run out of memory. An attacker could provide a single byte to a UTF16 decoder instantiated with UseBOM or ExpectBOM to trigger an infinite loop if the String function on the Decoder is called, or the Decoder is passed to golang.org/x/text/transform.String.
3) Prototype pollution (CVE-ID: CVE-2020-7598)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can inject and execute arbitrary script code.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
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.
5) 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.
6) 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.
