{"id":"GHSA-22q8-ghmq-63vf","summary":"libgit2-sys affected by memory corruption, denial of service, and arbitrary code execution in libgit2","details":"The [libgit2](https://github.com/libgit2/libgit2/) project fixed three security issues in the 1.7.2 release. These issues are:\n\n* The `git_revparse_single` function can potentially enter an infinite loop on a well-crafted input, potentially causing a Denial of Service. This function is exposed in the `git2` crate via the [`Repository::revparse_single`](https://docs.rs/git2/latest/git2/struct.Repository.html#method.revparse_single) method.\n* The `git_index_add` function may cause heap corruption and possibly lead to arbitrary code execution. This function is exposed in the `git2` crate via the [`Index::add`](https://docs.rs/git2/latest/git2/struct.Index.html#method.add) method.\n* The smart transport negotiation may experience an out-of-bounds read when a remote server did not advertise capabilities.\n\nThe `libgit2-sys` crate bundles libgit2, or optionally links to a system libgit2 library. In either case, versions of the libgit2 library less than 1.7.2 are vulnerable. The 0.16.2 release of `libgit2-sys` bundles the fixed version of 1.7.2, and requires a system libgit2 version of at least 1.7.2.\n\nIt is recommended that all users upgrade.\n","aliases":["RUSTSEC-2024-0013"],"modified":"2026-07-17T21:08:11.592435759Z","published":"2024-02-12T15:42:14Z","database_specific":{"cwe_ids":[],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-02-12T15:42:14Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/rust-lang/git2-rs/pull/1017"},{"type":"WEB","url":"https://github.com/rust-lang/git2-rs/commit/9e57876be78924c1e5f3f268bb599e3981fe58bb"},{"type":"PACKAGE","url":"https://github.com/rust-lang/git2-rs"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2024-0013.html"}],"affected":[{"package":{"name":"libgit2-sys","ecosystem":"crates.io","purl":"pkg:cargo/libgit2-sys"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.16.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/02/GHSA-22q8-ghmq-63vf/GHSA-22q8-ghmq-63vf.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L"}]}
