An issue was discovered in the mirage-crypto-ec package before 2.3.0 for OCaml. There is an EC public key out-of-bounds read for compressed points.
AnalysisAI
Out-of-bounds read in the mirage-crypto-ec OCaml cryptographic library (versions before 2.3.0) allows low-privileged network attackers to crash or disrupt services that parse compressed elliptic curve public keys. The flaw arises from insufficient bounds checking during compressed EC point deserialization, classified under CWE-125. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target service to accept and parse externally supplied compressed elliptic curve public keys - typically during TLS handshake, certificate validation, or ECDH key exchange. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L) reflects a medium-severity denial-of-service risk with no confirmed confidentiality or integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary fix is to upgrade mirage-crypto-ec to version 2.3.0 or later, which resolves the out-of-bounds read in compressed EC point handling. … Detailed patch versions, workarounds, and compensating controls in full report. |
