The public GPG keys here are only to check the integrity of a downloaded proprietary plugin, to prevent that someone could make HPLIP download and install a fake, malware plugin. HPLIP does not load such a key as long as the user does not try to download the plugin and HPLIP dos also not do any other downloads from the internet. The keys are actually only HP's public keys. No keys of the user are stored under ~/.hplip. So wrong permissions should be harmless here.
So what you should do for testing is whether you can still download the proprietary plugin with the stricter permissions (with your patch). If it still works, the stricter permissions could be generally used, but as the keys are only public keys from HP, the stricter permissions are not actually needed. If my assumptions are correct, I do not see a security issue here. Can someone from HP tell whether I am right? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1938442 Title: Wrong permissions on ~/.hplip/.gnupg Status in HPLIP: New Status in hplip package in Ubuntu: New Status in Fedora: Unknown Bug description: [Impact] * The directory ~/.hplip/.gnupg is readable by non-root users * This directory contains only public keys, but should still have the permissions changed to 700 for privacy reasons [Test Case] * Install hplip and run `hp-plugin -i` * ls -al ~/.hplip and observe that ~/.hplip/.gnupg has perms drwxr-xr-x * rm -rf ~/.hplip and install hplip from -proposed * run `hp-plugin -i` again * ls -al ~/.hplip and observe that ~/.hplip/.gnupg has perms drwx------ [Regression Potential] * Because of file permissions becoming more restrictive, it is possible that some other hplip binaries would fail to read the .gnupg directory * To ensure this isn't the case, testing should be done on different hplip use-cases to ensure they still function properly [Original Description] Hi, we have a report in Fedora - https://bugzilla.redhat.com/show_bug.cgi?id=1985251 - where Sergey found out that ~/.hplip/.gnupg directory has permissions 755 instead of 700. Perms 700 prevent accessing the dir by other users, because the dir can contain private keys. However, .gnupg dir contains only a public key used in GPG verification of HP plugin, so the matter isn't that critical, but it is good to have it fixed. The patch is attached.
