asn1_der: Processing of maliciously crafted length fields causes memory allocation SIGABRTsAffected versions of this crate tried to preallocate a vector for an arbitrary amount of bytes announced by the ASN.1-DER length field without further checks.
This allows an attacker to trigger a SIGABRT by creating length fields that announce more bytes than the allocator can provide.
The flaw was corrected by not preallocating memory.
smallvec: Buffer overflow in SmallVec::insert_manyA bug in the SmallVec::insert_many method caused it to allocate a buffer that was smaller than needed. It then wrote past the end of the buffer, causing a buffer overflow and memory corruption on the heap.
This bug was only triggered if the iterator passed to insert_many yielded more items than the lower bound returned from its size_hint method.
The flaw was corrected in smallvec 0.6.14 and 1.6.1, by ensuring that additional space is always reserved for each item inserted. The fix also simplified the implementation of insert_many to use less unsafe code, so it is easier to verify its correctness.
Thank you to Yechan Bae (@Qwaz) and the Rust group at Georgia Tech’s SSLab for finding and reporting this bug.
libsecp256k1: libsecp256k1 allows overflowing signatureslibsecp256k1 accepts signatures whose R or S parameter is larger than the secp256k1 curve order, which differs from other implementations. This could lead to invalid signatures being verified.
The error is resolved in 0.5.0 by adding a check_overflow flag.
ed25519-dalek: Double Public Key Signing Function Oracle Attack on `ed25519-dalek`Versions of ed25519-dalek prior to v2.0 model private and public keys as
separate types which can be assembled into a Keypair, and also provide APIs
for serializing and deserializing 64-byte private/public keypairs.
Such APIs and serializations are inherently unsafe as the public key is one of
the inputs used in the deterministic computation of the S part of the signature,
but not in the R value. An adversary could somehow use the signing function as
an oracle that allows arbitrary public keys as input can obtain two signatures
for the same message sharing the same R and only differ on the S part.
Unfortunately, when this happens, one can easily extract the private key.
Revised public APIs in v2.0 of ed25519-dalek do NOT allow a decoupled
private/public keypair as signing input, except as part of specially labeled
"hazmat" APIs which are clearly labeled as being dangerous if misused.
