What an attacker can do

The source says when a malformed OLE compound file with a version-valid EncryptionInfo stream is opened or passed to Decrypt, nine malformed-input classes reach unrecovered Go runtime panics instead of the documented error path, allowing an attacker to terminate the calling process. Vendor/CNA’s CVSS 3.1 assessment (base score 7.5/10) rates confidentiality and integrity impact as none; availability impact as high.
