Description

This security bulletin contains information about 8 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2021-38297)

CWE-ID: CWE-119 - Memory corruption

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


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

The vulnerability exists due to a boundary error. A remote attacker can trigger memory corruption via large arguments in a function invocation from a WASM module, when GOARCH=wasm GOOS=js is used.


2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2021-39293)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/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 improper validation of archive/zip in Go programming language when processing archive header. A remote attacker can pass a specially crafted file to the application and perform a denial of service (DoS) attack.


3) Resource exhaustion (CVE-ID: CVE-2021-33196)

CWE-ID: CWE-400 - Resource exhaustion

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 application does not properly control consumption of internal resources when parsing archives. A remote attacker can pass a specially crafted .zip file to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.


4) Buffer overflow (CVE-ID: CVE-2021-41771)

CWE-ID: CWE-119 - Memory corruption

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 attack.

The vulnerability exists in debug/macho of the Go standard library when using the debug/macho standard library (stdlib) and malformed binaries are parsed using Open or OpenFat. A remote attacker can send a specially crafted file to perform a denial of service attack.


5) Input validation error (CVE-ID: CVE-2021-41772)

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 in archive/zip Reader.Open. A remote attacker can pass specially crafted ZIP archive containing an invalid name or an empty filename field to the application and perform a denial of service (DoS) attack.


6) Resource exhaustion (CVE-ID: CVE-2022-23772)

CWE-ID: CWE-400 - Resource exhaustion

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 application does not properly control consumption of internal resources within the Rat.SetString(0 function in math/big. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


7) Incorrect authorization (CVE-ID: CVE-2022-23773)

CWE-ID: CWE-863 - Incorrect Authorization

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


The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists within cmd/go, which can misinterpret branch names that falsely appear to be version tags. This can lead to  a situation where an attacker can bypass implemented security restrictions and perform restricted actions, e.g. create tags when access was granted to create branches only.


8) Unchecked Return Value (CVE-ID: CVE-2022-23806)

CWE-ID: CWE-252 - Unchecked Return Value

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/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 unchecked return value within the Curve.IsOnCurve() function in crypto/elliptic. A remote attacker can force the application to incorrectly return true in situations with a big.Int value that is not a valid field element. As a result, an attacker can modify application flow, which can lead to unauthorized data modification or denial of service.
