CVE-2016-1541

Status: ModifiedHigh (8.8)—

Heap-based buffer overflow in the zip_read_mac_metadata function in archive_read_support_format_zip.c in libarchive before 3.2.0 allows remote attackers to execute arbitrary code via crafted entry-size values in a ZIP archive.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
