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.","epss":{"date":"2026-11-02","percentile":0.01037,"score":0.00105},"exploits":[],"kev":null,"metrics":[{"score":2.9,"severity":"low","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"}],"modifiedAt":1793645699689,"publishedAt":1784673698128,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:43818"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:69553"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-16517"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2505492"}],"remediation":[],"revision":"3789f6e02b561baa49f21a6e82dc416acbf54bab772762ee7b35583e921df5e2","sources":[{"modifiedAt":1793645699689,"name":"CNA: redhat","retrievedAt":1793646547783,"url":"https://www.cve.org/CVERecord?id=CVE-2026-16517"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793646553193,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-16517"}],"ssvc":{"assessedAt":1784724288802,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Libarchive: libarchive: signed integer overflow in archive_write_zip_header","updatedAt":1793646553193}
