CVE-2021-29948

Signatures are written to disk before and read during verification, which might be subject to a race condition when a malicious local process or user is replacing the file. This vulnerability affects Thunderbird 78.10...

nettle: Out of bounds memory access in signature verification

A flaw was found in Nettle, where several Nettle signature verification functions GOST DSA, EDDSA & ECDSA result in the Elliptic Curve Cryptography point ECC multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an...

GO-2021-0090 Denial of service in github.com/tendermint/tendermint

Proposed commits may contain signatures for blocks not contained within the commit. Instead of skipping these signatures, they cause failure during verification. A malicious proposer can use this to force consensus failures...

GO-2020-0012 Panic due to improper verification of cryptographic signatures in golang.org/x/crypto/ssh

An attacker can craft an ssh-ed25519 or [email protected] public key, such that the library will panic when trying to verify a signature with it. If verifying signatures using user supplied public keys, this may be used as a denial of service vector...

GO-2020-0047 Weak hash (SHA-1) in github.com/RobotsAndPencils/go-saml

XML Digital Signatures generated and validated using this package use SHA-1, which may allow an attacker to craft inputs which cause hash collisions depending on their control over the input...

GO-2020-0011

When decrypting JsonWebEncryption objects with multiple recipients or JsonWebSignature objects with multiple signatures the Decrypt and Verify methods do not indicate which recipient or signature was valid. This may lead a caller to rely on protected headers from an invalid recipient or signature...

UBUNTU-CVE-2021-23992

Thunderbird did not check if the user ID associated with an OpenPGP key has a valid self signature. An attacker may create a crafted version of an OpenPGP key, by either replacing the original user ID, or by adding another user ID. If Thunderbird imports and accepts the crafted key, the Thunderbi...

A flaw was found in Nettle in versions before 3.7.2 where several Nettle signature verification functions (GOST DSA EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being called with out-of-range scalers possibly resulting in incorrect results. This flaw allows an attacker to force an invalid signature causing an assertion failure or possible validation. The highest threat to this vulnerability is to confidentiality integrity as well as system availability.
