…with Git The V2/V3 decoder truncated entry names longer than 4095 bytes because it trusted the 12-bit length field. Git falls back to strlen (scanning for the NUL terminator) when the field is saturated at 0xFFF; do the same here so long paths round-trip correctly. The V4 encoder used a path.Dir heuristic for prefix compression, which diverges from Git's byte-level longest-common-prefix algorithm. Replace it with a common-prefix computation so the output matches what upstream produces. Signed-off-by: Paulo Gomes <paulo@entire.io> Assisted-by: Claude Opus 4.6 <noreply@anthropic.com>
The treeExtensionDecoder.readEntry early-returned on invalidated entries (entry_count == -1) before consuming the subtree count and newline, leaving stale bytes in the stream that corrupted subsequent entries. Move the invalidation check after fully parsing the entry line so the reader is always left at the correct position. Signed-off-by: Paulo Gomes <paulo@entire.io>

A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (`go-git` supports only `v2` and `v3`) are not vulnerable to this issue. An attacker able to supply a crafted `.git/index` file can cause applications using go-git to panic while reading the index. If the application does not recover from panics, this results in process termination, leading to a denial-of-service (DoS) condition. Exploitation requires the ability to modify or inject a Git index file within the local repository in disk. This typically implies write access to the `.git` directory. ##### Patches Users should upgrade to `v5.17.1`, or the latest `v6` [pseudo-version](https://go.dev/ref/mod#pseudo-versions), in order to mitigate this vulnerability. ##### Credit go-git maintainers thank @​kq5y for finding and reporting this issue privately to the `go-git` project. #### Severity - CVSS Score: 2.8 / 10 (Low) - Vector String: `CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L` #### References - [https://github.com/go-git/go-git/security/advisories/GHSA-gm2x-2g9h-ccm8](https://github.com/go-git/go-git/security/advisories/GHSA-gm2x-2g9h-ccm8) - [https://github.com/go-git/go-git](https://github.com/go-git/go-git) This data is provided by [OSV](https://osv.dev/vulnerability/GHSA-gm2x-2g9h-ccm8) and the [GitHub Advisory Database](https://github.com/github/advisory-database) ([CC-BY 4.0](https://github.com/github/advisory-database/blob/main/LICENSE.md)). </details> --- ### go-git: Maliciously crafted idx file can cause asymmetric memory consumption [CVE-2026-34165](https://nvd.nist.gov/vuln/detail/CVE-2026-34165) / [GHSA-jhf3-xxhw-2wpp](GHSA-jhf3-xxhw-2wpp) <details> <summary>More information</summary> #### Details ##### Impact A vulnerability has been identified in which a maliciously crafted `.idx` file can cause asymmetric memory consumption, potentially exhausting available memory and resulting in a Denial of Service (DoS) condition.

A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (`go-git` supports only `v2` and `v3`) are not vulnerable to this issue. An attacker able to supply a crafted `.git/index` file can cause applications using go-git to panic while reading the index. If the application does not recover from panics, this results in process termination, leading to a denial-of-service (DoS) condition.
