CVE-2026-47734 Dulwich has unbounded memory allocation in receive-pack from crafted thin packs

Dulwich is a pure-Python implementation of the Git file formats and protocols. Starting in version 0.1.0 and prior to version 1.2.5, a client with push access could push a tiny crafted thin pack 174 bytes whose delta header declares a huge destsize. When dulwich ingested it via addthinpack /...

CVE-2026-47734

Dulwich prior to 1.2.5 is vulnerable to an unbounded memory allocation in receive-pack when processing a crafted thin pack. A tiny push (~174 bytes) can declare a huge dest_size in the delta header, causing add_thin_pack / apply_delta to allocate hundreds of MB regardless of actual data. Impacted...
