Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of the Go package github.com/ipfs/go-bitfield before 1.1.0 can panic when untrusted input is passed as the size argument to NewBitfield or FromBytes, if the size is negative or not a multiple of 8. An attacker who can supply that value can crash the affected process, causing a denial of service. Upgrade to go-bitfield 1.1.0, which returns an error for invalid sizes. Without upgrading, ensure the size is a non-negative multiple of 8 before calling these functions.
