Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Out-of-bounds Write: Array-shifting operations during element insertion calculated slice boundaries using obsolete array size variables, leading to potential heap memory corruption. Developers must ensure structure size metadata is incremented before executing index-shifting loops.
Out-of-bounds Write: Manual slice writes during dynamic memory expansion allowed writes past allocated buffers. Replacing raw slice assignments with explicit, loop-driven push sequences prevents incorrect size calculation exploits.
Path Traversal: Extraction of untrusted ZIP archives permitted files to be written outside the target directory (Zip Slip). Standard library paths must undergo canonicalization and verification against an expected directory prefix.
