Description

This security bulletin contains information about 4 vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2021-33194)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to infinite loop. A remote attacker can pass crafted ParseFragment  input to the application, consume all available system resources and cause denial of service conditions.


2) Input validation error (CVE-ID: CVE-2021-44716)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


3) Uncontrolled Recursion (CVE-ID: CVE-2021-31525)

CWE-ID: CWE-674 - Uncontrolled Recursion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a DoS attack.

The vulnerability exists due to uncontrolled recursion when processing HTTP headers. A remote attacker can send a large header to ReadRequest or ReadResponse and perform a denial of service (DoS) attack.


4) Infinite loop (CVE-ID: CVE-2021-27918)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to infinite loop when using xml.NewTokenDecoder with a custom TokenReader. A remote attacker can trick a victim to open a specially crafted XML content and cause denial of service conditions.
