The borsh serialization of the HashMap did not follow the borsh specification. It potentially produced non-canonical encodings dependent on insertion order. It also did not perform canonicty checks on decoding. This can result in consensus splits and cause equivalent objects to be considered distinct. This was patched in 0.15.1.

Affected versions allow populating a DistributedSlice of T with elements of an arbitrary other type that coerces to T. For example, elements of type `&&str` could end up in a slice of type `[&str]`, since `&&str` coerces to `&str` via a deref coercion. The flaw was corrected by implementing typechecking for distributed slice elements in such a way that coercion no longer occurs. The element's type must be a subtype of the slice's declared element type.

### Summary A security vulnerability has been identified in GitHub CLI that could create or overwrite files in unintended directories when users download a malicious GitHub Actions workflow artifact through `gh run download`. ### Details This vulnerability stems from a GitHub Actions workflow artifact named `..` when downloaded using `gh run download`. The artifact name and `--dir` flag are used to determine the artifact’s download path. When the artifact is named `..`, the resulting files within the artifact are extracted exactly 1 directory higher than the specified `--dir` flag value. In `2.63.1`, `gh run download` will not download artifacts named `..` and `.` and instead exit with the following error message: ``` error downloading ..: would result in path traversal ``` ### Impact Successful exploitation heightens the risk of local path traversal attack vectors exactly 1 directory higher than intended. ### Remediation and Mitigation 1. Upgrade `gh` to `2.63.1` 2. Implem...

Proposals from Google and Apple drastically reduce the life cycle of certificates, which should mean more oversight — and hopefully better control.
