CVE-2021-39158

Status: ModifiedHigh (8.8)—

NVCaffe's python required dependencies list used to contain `gfortran`version prior to 0.17.4, entry which does not exist in the repository pypi.org. An attacker could potentially have posted malicious files to pypi.org causing a user to install it within NVCaffe.

CVSS
