radare2 4.5.0 misparses signature information in PE files, causing a segmentation fault in r_x509_parse_algorithmidentifier in libr/util/x509.c. This is due to a malformed object identifier in IMAGE_DIRECTORY_ENTRY_SECURITY.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - radare2 4.5.0 misparses signature information in PE files, causing a segmentation fault in     r_x509_parse_algorithmidentifier in libr/util/x509.c. This is due to a malformed object identifier in     IMAGE_DIRECTORY_ENTRY_SECURITY. (CVE-2020-17487)

Note that Nessus relies on the presence of the package as reported by the vendor.
