Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Incorrect Regular Expression (CVE-ID: CVE-2022-24921)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in regexp.Compile in Go. A remote attacker can pass specially crafted input to the application and perform regular expression denial of service (ReDoS) attack.
2) NULL pointer dereference (CVE-ID: CVE-2020-29652)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when processing an authentication request message for the “gssapi-with-mic” method. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
3) Buffer overflow (CVE-ID: CVE-2022-24675)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the Golang's library encoding/pem. A remote attacker can send to victim a large (more than 5 MB) PEM input to cause a stack overflow in Decode and perform a denial of service (DoS) attack.
4) Integer overflow (CVE-ID: CVE-2022-28327)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to integer overflow in the Golang's library crypto/elliptic. A remote attacker can send a specially crafted scalar input longer than 32 bytes to cause P256().ScalarMult or P256().ScalarBaseMult to panic and perform a denial of service attack.
5) 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.
6) Incorrect authorization (CVE-ID: CVE-2022-23773)
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.
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.
