kernel: hash collisions in the IPv6 connection lookup table

A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6...

GHSA-5R98-F33J-G8H7 pnpm incorrectly parses tar archives relative to specification

Summary It is possible to construct a tarball that, when installed via npm or parsed by the registry is safe, but when installed via pnpm is malicious, due to how pnpm parses tar archives. Details The TAR format is an append-only archive format, and as such, the specification for how to update a...

[H] Address collisions due to lack of check on the salt parameter

Lines of code Vulnerability details Impact In ConstAddressDeployer, functions deploy and deployAndInit do not check for the same salt value being passed in by different users. This can lead to address collisions. If someone passes the same salt value as someone else, even with different bytecode...
