06 Feb 2024 — libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Using well-crafted inputs to `git_index_add` can cause heap corruption that could be leveraged for arbitrary code execution. There is an issue in the `has_dir_name` function in `src/libgit2/index.c`, which frees an entry that should not be freed. The freed entry is later used and overwritten with potentially bad actor-controlled data leadi... • https://github.com/libgit2/libgit2/releases/tag/v1.6.5 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

06 Feb 2024 — libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Using well-crafted inputs to `git_revparse_single` can cause the function to enter an infinite loop, potentially causing a Denial of Service attack in the calling application. The revparse function in `src/libgit2/revparse.c` uses a loop to parse the user-provided spec string. There is an edge-case during parsing that allows a bad actor to... • https://github.com/libgit2/libgit2/commit/add2dabb3c16aa49b33904dcdc07cd915efc12fa • CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.9EPSS: 0%CPEs: 2EXPL: 0CVE-2023-22742 – libgit2 fails to verify SSH keys by default
https://notcve.org/view.php?id=CVE-2023-22742
20 Jan 2023 — libgit2 is a cross-platform, linkable library implementation of Git. When using an SSH remote with the optional libssh2 backend, libgit2 does not perform certificate checking by default. Prior versions of libgit2 require the caller to set the `certificate_check` field of libgit2's `git_remote_callbacks` structure - if a certificate check callback is not set, libgit2 does not perform any certificate checking. This means that by default - without configuring a certificate check callback, clients will not perf... • http://www.openwall.com/lists/oss-security/2023/11/06/5 • CWE-347: Improper Verification of Cryptographic Signature •
