Attackers can\ncraft a malicious repository whose popped stash writes a payload into\n.git/hooks/post-checkout, achieving code execution on the next checkout.\nDulwich from 0.23.1 before 1.2.8 contains a path traversal vulnerability\nin CommitFilter._apply_index_filter() that allows attackers to write\nfiles outside the working directory via symlinks persisting between\ncommits. Attackers can craft a repository where an ancestor commit's\nsymlink redirects a descendant commit's file writes during\nfilter_branch, enabling code execution by writing into .git/hooks.\nDulwich before 1.2.9 contains a denial of service vulnerability in\nPack.resolve_object that allows attackers to cause infinite recursion\nvia self-referential OFS_DELTA objects. Attackers can supply a malicious\npackfile with an OFS_DELTA delta_offset of 0 to exhaust CPU during\nclone, fetch, or cat-file operations.\nDulwich before 1.2.9 fails to validate DOS drive letter prefixes in Git\ntree path elements on Windows, allowing arbitrary file write. Attackers\ncan craft a malicious repository with a tree entry named 'C:' that\nbypasses NTFS validation and writes files outside the worktree to\nachieve remote code execution.\nDulwich from 0.24.0 before 1.2.8 contains a symlink following\nvulnerability in porcelain.checkout(paths=[...]) that allows attackers\nto write arbitrary files by abusing raw os.open without O_NOFOLLOW.\nAttackers can craft a repository where a worktree symlink points to\n.git/hooks/post-checkout, so restoring the file from a tag writes a\nmalicious hook for code execution.\n","supportingMedia":null}],"references":[{"url":"https://advisories.mageia.org/MGASA-2026-0589.html","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["advisory"]},{"url":"https://bugs.mageia.org/show_bug.cgi?id=35907","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["issue"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/YORLARHG3RTPSDHI7QFLTZNL67NVZCN7/","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["url"]},{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-555p-6grf-mh7f","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["advisory"]},{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-xrvj-v92f-53gj","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["advisory"]},{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-cm62-gvxx-vmxx","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["advisory"]},{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-5fqc-mrg8-w798","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["advisory"]},{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-35mr-4567-66vg","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["advisory"]},{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-8mcx-5rqc-vhmf","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["advisory"]},{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-8w8g-wq8h-fq33","name":"Updated python-dulwich \u0026 rust-similar3 packages fixes security vulnerabilities","tags":["advisory"]}],"metrics":null,"problemTypes":null,"affected":[{"vendor":"Mageia","product":"rust-similar3","collectionURL":"pkg:rpm/mageia/rust-similar3?arch=source\u0026distro=mageia-10","packageName":"rust-similar3","repo":"","defaultStatus":"","versions":[{"version":"0","status":"affected","versionType":"ecosystem","lessThan":"","lessThanOrEqual":"","changes":null},{"version":"3.1.1-1.mga10","status":"unaffected","versionType":"ecosystem","lessThan":"","lessThanOrEqual":"","changes":null}],"cpes":null,"modules":null,"programFiles":null,"platforms":null},{"vendor":"Mageia","product":"python-dulwich","collectionURL":"pkg:rpm/mageia/python-dulwich?arch=source\u0026distro=mageia-10","packageName":"python-dulwich","repo":"","defaultStatus":"","versions":[{"version":"0","status":"affected","versionType":"ecosystem","lessThan":"","lessThanOrEqual":"","changes":null},{"version":"1.2.21-1.1.mga10","status":"unaffected","versionType":"ecosystem","lessThan":"","lessThanOrEqual":"","changes":null}],"cpes":null,"modules":null,"programFiles":null,"platforms":null}],"cpeApplicability":null,"rejectedReasons":null,"replacedBy":null},"adp":null}}
