Insufficient archive validation can cause out-of-bounds reads in archives containing Rc/Arc
Shared pointer validation keyed already-validated pointees by their address and type, but did not include pointer metadata. For unsized pointees, an archive could therefore contain multiple `Rc`, `Arc`, or weak pointers that shared a data address but used dif…

Potential undefined behavior with Signature from a buffer-created BlameHunk
When a `Blame` is created via `Blame::blame_buffer()`, and a `BlameHunk` is retrieved, the pointers to the original author, original committer, final author, and final committer may be null if unavailable. The corresponding `BlameHunk` methods then create `Si…

Potential use-after-free due to lack of panic safety in `LruCache::pop()`
`LruCache::pop()` in `lru` was not panic-safe. If the `Drop` implementation of a stored key panics during `pop()`, `self.detach()` is never called, leaving dangling pointers in the internal doubly-linked list. A subsequent cache operation that triggers evicti…

Potential undefined behavior when calling Remote::list()
When calling `Remote::list()` for a remote of a git repository, when that remote does not advertise any references, git2 passes a null pointer to the unsafe function `slice::from_raw_parts()`. Based on the safety section documentation of function, data must b…

oxidize-pdf: NaN/inf bypass in colour content-stream emission causes PDF rejection (DoS)
### Impact `oxidize-pdf` defines `Color` as a `pub enum` with public tuple-struct variants `Rgb(f64, f64, f64)`, `Gray(f64)`, and `Cmyk(f64, f64, f64, f64)`. The constructors `Color::rgb`, `Color::gray`, and `Color::cmyk` clamp incoming components to `[0.0, 1…

Insufficient archive validation can cause out-of-bounds reads in archives containing hash tables
The archive validator could accept certain malformed relative pointers and invalid `ArchivedHashTable` states. In particular, the hash table verifier did not ensure that the number of occupied buckets matched the table's declared length. A crafted archive cou…
