USN-5546-1: OpenJDK vulnerabilities

Neil Madden discovered that OpenJDK did not properly verify ECDSA signatures. A remote attacker could possibly use this issue to insert, edit or obtain sensitive information. This issue only affected OpenJDK 17 and OpenJDK 18. CVE-2022-21449 It was discovered that OpenJDK incorrectly limited memo...

USN-5546-1 openjdk-8, openjdk-lts, openjdk-17, openjdk-18 vulnerabilities

Neil Madden discovered that OpenJDK did not properly verify ECDSA signatures. A remote attacker could possibly use this issue to insert, edit or obtain sensitive information. This issue only affected OpenJDK 17 and OpenJDK 18. CVE-2022-21449 It was discovered that OpenJDK incorrectly limited memo...

Direct usage of ecrecover allows signature malleability

Lines of code Vulnerability details Impact The permit function of ERC20Permit calls the Solidity ecrecover function directly to verify the given signatures. However, the ecrecover EVM opcode allows malleable non-unique signatures and thus is susceptible to replay attacks. This can leads to permit...

Incorrect check for signature malleability

Lines of code Vulnerability details Impact Sig.recover has an Incorrect check: c.v != 27 || c.v != 28. Thus, Sig.recover always reverts. Proof of Concept c.v != 27 || c.v != 28 is always true function recoverbytes32 h, Components calldata c internal pure returns address // EIP-2 and malleable...

Java Psychic Signatures

Oracle Java SE versions 15, 17 and 18 and Oracle GraalVM Enterprise Edition versions 21.3.1 and 22.0.0.2 do not properly verify Ellipic Curve Digital Signature Algorithm ECDSA based signatures. By forcing the r and s components values of the signature to zero, an attacker could forge a valid...

use ECDSA helper library instead of ecrecover

Lines of code Vulnerability details use ECDSA helper library instead of ecrecover the function permit adds approval for a spender for a certain amount of value use of ecrecover to validate signatures without a nonce will allow signatures to be replayed to add additional approvals due to signature...

wolfCrypt leaks cryptographic information via timing side channel

wolfSSL and wolfCrypt 4.0.0 and earlier when configured without --enable-fpecc, --enable-sp, or --enable-sp-math contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about th...

GO-2022-0217 Denial of service affecting P-521 and P-384 curves in crypto/elliptic

A DoS vulnerability in the crypto/elliptic implementations of the P-521 and P-384 elliptic curves may let an attacker craft inputs that consume excessive amounts of CPU. These inputs might be delivered via TLS handshakes, X.509 certificates, JWT tokens, ECDH shares or ECDSA signatures. In some...

CVE-2022-24884

ecdsautils is a tiny collection of programs used for ECDSA keygen, sign, verify. ecdsaverifypreparelegacy does not check whether the signature values r and s are non-zero. A signature consisting only of zeroes is always considered valid, making it trivial to forge signatures. Requiring multiple...

GO-2022-0435 Panic due to large inputs affecting P-256 curves in crypto/elliptic

A crafted scalar input longer than 32 bytes can cause P256.ScalarMult or P256.ScalarBaseMult to panic. Indirect uses through crypto/ecdsa and crypto/tls are unaffected. amd64, arm64, ppc64le, and s390x are unaffected...
