Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
Updated 13.04.2022
Added fixed version.
Updated 14.06.2022
Added vulnerabilities #2-3.
1) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU62039
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-27191
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in golang.org/x/crypto/ssh before 0.0.0-20220314234659-1baeb1ce4c0b, as used in Go programming language. A remote attacker can crash a server in certain circumstances involving AddHostKey.

2) Integer overflow
EUVDB-ID: #VU64269
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-28327
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe 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) Buffer overflow
EUVDB-ID: #VU64266
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-24675
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe 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.
