Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Incomplete path canonicalization validation allows archive entries containing directory traversal sequences to escape the extraction destination directory, potentially overwriting critical host files. This is a recurring theme also represented in CVE-2018-1002202.
Use of Insufficiently Random Values: Generating cryptographic salts and initialization vectors using standard, predictable PRNGs (java.util.Random) instead of SecureRandom exposes encrypted archives to brute-force attacks and predictable key-derivation.
Cryptographic Issues: Flaws in parsing streams where pushed-back bytes are incorrectly included in MAC calculations can lead to incorrect validation of corrupted or modified files, contributing to broader integrity bypass surfaces (CVE-2023-22899).
