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.

Security readout for executives and security teams

CVE-2013-2100 is a Gentoo Portage HTTPS trust failure. The affected urlopen code did not verify server certificates, so an attacker positioned between a system and its package source could impersonate the server and alter binary package lists. Exposure is most likely on Gentoo systems using the affected Portage 2.1.12 code path for HTTPS-based binary package list retrieval. Systems not using Gentoo Portage or not using the vulnerable binary package workflow are less likely exposed. Prioritize remediation for Gentoo systems that rely on binary package distribution across untrusted networks. The business risk is supply-chain integrity: altered package lists can influence what software systems install or trust. Mitigation focus: Review Gentoo GLSA-201507-16 for official remediation guidance.; Upgrade or patch Portage according to Gentoo vendor instructions.; Inventory systems for Gentoo Portage 2.1.12 usage..
