There are 6 open security issues in bookworm.
1 important issue:
- CVE-2025-14505:
The ECDSA implementation of the Elliptic package generates incorrect signatures if an interim value of 'k' (as computed based on step 3.2 of RFC 6979 https://datatracker.ietf.org/doc/html/rfc6979 ) has leading zeros and is susceptible to cryptanalysis, which can lead to secret key exposure. This happens, because the byte-length of 'k' is incorrectly computed, resulting in its getting truncated during the computation. Legitimate transactions or communications will be broken as a result. Furthermore, due to the nature of the fault, attackers could–under certain conditions–derive the secret key, if they could get their hands on both a faulty signature generated by a vulnerable version of Elliptic and a correct signature for the same inputs. This issue affects all known versions of Elliptic (at the time of writing, versions less than or equal to 6.6.1).
5 issues left for the package maintainer to handle:
- CVE-2024-42459:
(needs triaging)
In the Elliptic package 6.5.6 for Node.js, EDDSA signature malleability occurs because there is a missing signature length check, and thus zero-valued bytes can be removed or appended.
- CVE-2024-42460:
(needs triaging)
In the Elliptic package 6.5.6 for Node.js, ECDSA signature malleability occurs because there is a missing check for whether the leading bit of r and s is zero.
- CVE-2024-42461:
(needs triaging)
In the Elliptic package 6.5.6 for Node.js, ECDSA signature malleability occurs because BER-encoded signatures are allowed.
- CVE-2024-48948:
(needs triaging)
The Elliptic package 6.5.7 for Node.js, in its for ECDSA implementation, does not correctly verify valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. This leads to valid signatures being rejected. Legitimate transactions or communications may be incorrectly flagged as invalid.
- CVE-2024-48949:
(needs triaging)
The verify function in lib/elliptic/eddsa/index.js in the Elliptic package before 6.5.6 for Node.js omits "sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()" validation.
