Migration Toolkit for Runtimes 1.1.1 ZIP artifactsSecurity Fix(es): htmlUnit: Stack overflow crash causes Denial of Service (DoS) (CVE-2023-2798) zip4j: does not always check the MAC when decrypting a ZIP archive (CVE-2023-22899) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Zip4j through 2.11.2, as used in Threema and other products, does not always check the MAC when decrypting a ZIP archive.

zip4j up to v2.10.0 can throw various uncaught exceptions while parsing a specially crafted ZIP file, which could result in an application crash. This could be used to mount a denial of service attack against services that use zip4j library.

zip4j before 1.3.3 is vulnerable to directory traversal, allowing attackers to write to arbitrary files via a ../ (dot dot slash) in a Zip archive entry that is mishandled during extraction. This vulnerability is also known as 'Zip-Slip'.
