{"id":"AZL-93231","summary":"CVE-2026-16517 affecting package libarchive 3.7.7-7","details":"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.","modified":"2026-08-30T05:26:50Z","published":"2026-07-21T23:17:00Z","upstream":["CVE-2026-16517"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16517"}],"affected":[{"package":{"name":"libarchive","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libarchive"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.7.7-7"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-93231.json"}}],"schema_version":"1.9.0"}
