In Gentoo Portage before 3.0.47, there is missing PGP validation of executed code: the standalone emerge-webrsync downloads a .gpgsig file but does not perform signature verification. Unless emerge-webrsync is used, Portage is not vulnerable. En Gentoo Portage anterior a 3.0.47, falta la validación PGP del código ejecutado: el emerge-webrsync independiente descarga un archivo .gpgsig pero no realiza la verificación de firma. • https://bugs.gentoo.org/597800 https://gitweb.gentoo.org/proj/portage.git/tree/NEWS https://wiki.gentoo.org/wiki/Portage • CWE-347: Improper Verification of Cryptographic Signature •

Gentoo Portage through 2.3.84 allows local users to place a Trojan horse plugin in the /usr/lib64/nagios/plugins directory by leveraging access to the nagios user account, because this directory is writable in between a call to emake and a call to fowners. Gentoo Portage versiones hasta 2.3.84, permite a usuarios locales colocar un complemento de tipo caballo de Troya en el directorio /usr/lib64/nagios/plugins al aprovechar el acceso a la cuenta de usuario nagios, porque este directorio es escribible entre una llamada a emake y una llamada a Fowners. • http://www.openwall.com/lists/oss-security/2020/01/21/1 https://bugs.gentoo.org/692492 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The urlopen function in pym/portage/util/_urlopen.py in Gentoo Portage 2.1.12, when using HTTPS, does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and modify binary package lists via a crafted certificate.
