Description
This security bulletin contains information about 3 vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2022-24675)
CWE-ID: CWE-120 - Buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
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) Incorrect Regular Expression (CVE-ID: CVE-2022-24921)
CWE-ID: CWE-185 - Incorrect Regular Expression
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 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.
3) Integer overflow (CVE-ID: CVE-2022-28327)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
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.
