Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-787: Out-of-bounds Write, where the product writes data past the end, or before the beginning, of the intended buffer. In Duplicate Advisory, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-6mw6-mj76-grwc. This link is maintained to preserve external references. ### Original Description A flaw was found in gix-date. The `gix_date::parse::TimeBuf::as_str` function can generate strings containing invalid non-UTF8 characters. This issue violates the internal safety invariants of the `TimeBuf` component, leading to undefined behavior when these malformed strings are subsequently processed. This could potentially result in application instability or other unforeseen consequences.
