1) 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.
2) 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.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-29526)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the Faccessat function can incorrectly report that a file is accessible, when called with a non-zero flags parameter. An attacker can bypass implemented security restrictions.
4) Input validation error (CVE-ID: CVE-2022-21698)
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 within method label cardinality. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Overly permissive cross-domain whitelist (CVE-ID: CVE-2022-1996)
The vulnerability allows a remote attacker to bypass the CORS protection mechanism.
The vulnerability exists due to incorrect processing of the "Origin" HTTP header that is supplied within HTTP request. A remote attacker can supply arbitrary value via the "Origin" HTTP header, bypass implemented CORS protection mechanism and perform cross-site scripting attacks against the vulnerable application.
