Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2021-44716)
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.
2) Input validation error (CVE-ID: CVE-2021-41772)
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.
3) Buffer overflow (CVE-ID: CVE-2021-41771)
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.
4) Buffer overflow (CVE-ID: CVE-2021-38297)
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.
5) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2021-39293)
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.
6) Race condition (CVE-ID: CVE-2021-36221)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition in net/http/httputil ReverseProxy when handling ErrAbortHandler events. A remote attacker can trigger a race condition and crash the ReverseProxy.
7) Resource exhaustion (CVE-ID: CVE-2021-44717)
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 requests. A remote attacker can send multiple HTTP/2 requests to the server and exhaust all available memory resources.
8) Resource exhaustion (CVE-ID: CVE-2021-33196)
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.
