Malicious Python Package Hides Sliver C2 Framework in Fake Requests Library Logo

Cybersecurity researchers have identified a malicious Python package that purports to be an offshoot of the popular requests library and has been found concealing a Golang-version of the Sliver command-and-control C2 framework within a PNG image of the project's logo. The package employing this...

Rootstock Labs: Crafted smart contract can take 1.5 minutes to execute due to inefficient CODESIZE implementation

The crafted smart contract can take 1.5 minutes to execute due to an inefficient implementation of the CODESIZE operation in the VM. The issue was caused by the VM.doCODESIZE method, which retrieved the entire code array instead of just the code length. This behavior could be exploited to transfe...

Improper Input Validation

vyper is vulnerable to Improper Input Validation. The vulnerability is due to using the slice builtin with msg.data, self.code, or .code as the buffer argument, when either the start or length arguments have side-effects, allowing an attacker to manipulate the smart contract's behaviour or extrac...

vyper performs incorrect topic logging in raw_log

Summary Incorrect values can be logged when rawlog builtin is called with memory or storage arguments to be used as topics. A contract search was performed and no vulnerable contracts were found in production. In particular, no uses of rawlog were found at all in production; it is apparently not ...

GHSA-3WHQ-64Q2-QFJ6 vyper performs double eval of raw_args in create_from_blueprint

Summary Using the createfromblueprint builtin can result in a double eval vulnerability when rawargs=True and the args argument has side-effects. A contract search was performed and no vulnerable contracts were found in production. In particular, the rawargs variant of createfromblueprint was not...

vyper default functions don't respect nonreentrancy keys

Summary Prior to v0.3.0, default functions did not respect the @nonreentrancy decorator and the lock was not emitted. This is a known bug and was already visible in the issue tracker https://github.com/vyperlang/vyper/issues/2455, but it is being re-issued as an advisory so that tools relying on...

vyper performs multiple eval of `sqrt()` argument built in

Summary Using the sqrt builtin can result in multiple eval evaluation of side effects when the argument has side-effects. The bug is more difficult but not impossible! to trigger as of 0.3.4, when the unique symbol fence was introduced https://github.com/vyperlang/vyper/pull/2914. A contract sear...
