| CVE-2024-27355 | Hig | 0.42 | 7.5 | 0.01 | Mar 1, 2024 | An issue was discovered in phpseclib 1.x before 1.0.23, 2.x before 2.0.47, and 3.x before 3.0.36. When processing the ASN.1 object identifier of a certificate, a sub identifier may be provided that leads to a denial of service (CPU consumption for decodeOID). | ||
