NVD Description

Note: Versions mentioned in the description apply only to the upstream libarchive-devel package and not the libarchive-devel package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption.
