Forge: Ed25519 signature verification accepts small-order public keys

### Summary `ed25519.verify()` does not reject public keys of small order, such as the identity point. Under such a key, a signature with `S = 0` and a small-order `R` verifies for many messages, or for every message with the identity key, without any private key. Fixed in node-forge 1.4.3. ### Details `crypto_sign_open()` in `lib/ed25519.js` decodes the public key `A` with `unpackneg()`, which only checks that the point is on the curve, and then checks `R == [S]B - [k]A`…

Forge: ReDoS in forge.http response header and cookie trimming

`forge.http` trims response header and `Set-Cookie` values with the regular expression `/\s*$/`, which takes quadratic time on a long run of whitespace followed by another character. A server or on-path attacker can block a `forge.http` client for minutes with one large response header. Fixed in node-forge 1.4.3. ### Details `_trimString()` in `lib/http.js` removes trailing whitespace with `str.replace(/\s*$/, '')`. On a string of n whitespace characters followed by a…

Forge: TLS client crash on an unsupported ServerHello compression method

### Summary A `forge.tls` client accepts any compression method in the ServerHello, although it only offers no compression. An unknown method makes `connection.process()` throw an uncaught `Error` when the client handles ServerHelloDone, before the server is authenticated. A malicious server or an on-path attacker can use this to terminate a Node.js process. Fixed in node-forge 1.4.3. ### Details The client's ClientHello offers only the `null` compression method…

Linux Kernel: Mehrere Schwachstellen

In the Linux kernel, the following vulnerability has been resolved: inet: reject unhashed sockets during established lookups TCP established ehash lookups are lockless. The socket caches involved use SLAB_TYPESAFE_BY_RCU, so memory can be reused before an RCU reader that retained its old address has finished. After a tuple match, __inet_lookup_established() and __inet6_lookup_established() acquire a reference and repeat the tuple check. They do not check whether the new…

xen-netback: Fix XenBus connection failure cleanup

In the Linux kernel, the following vulnerability has been resolved: xen-netback: Fix XenBus connection failure cleanup xenvif_get_stats and xenvif_get_ethtool_stats capture vif->num_queues under rcu_read_lock. We need to unpublish vif->num_queues before synchronize_net to ensure that readers that come afterwards will not read a non-zero vif->num_queues and attempt to access invalid queues. This is the same cleanup algorithm as used in backend_disconnect and added in commit…

git: Mehrere Schwachstellen

Affected versions of Git have a heap buffer overflow in the three-way merge code (xdiff), which an attacker can trigger through a repository they control. When Git merges a file, it first adds up the size of the merged output, allocates a buffer of that size, and then writes the output into it. That total was kept in a 32-bit signed integer. The conflict-marker-size attribute, which can be set from a committed .gitattributes file, accepts any positive integer, and the…
