Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU64266
Risk: Low
CVSSv4.0: 1.2 [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]
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.
MitigationInstall updates from vendor's repository.
