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","published":"2024-02-12T15:42:14Z","modified":"2026-09-10T03:50:05.143860663Z","cvss":{"score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"libgit2-sys","fixedVersion":"0.16.2"}],"fix":{"url":"https://github.com/rust-lang/git2-rs/pull/1017","label":"rust-lang/git2-rs#1017"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:50:05.143860663Z"}}
