NVD Description

Note: Versions mentioned in the description apply only to the upstream dulwich package and not the dulwich package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Dulwich from 0.23.1 before 1.2.8 contains a path traversal vulnerability in CommitFilter._apply_index_filter() that allows attackers to write files outside the working directory via symlinks persisting between commits. Attackers can craft a repository where an ancestor commit's symlink redirects a descendant commit's file writes during filter_branch, enabling code execution by writing into .git/hooks.
