In short, I found anomaly in Fedora 37 and would like to know if it is vulnerability.
As root type in terminal: dnf update If there is kernel update, watch stdout and stderr for: ##On Mon Aug 14 05:33:29 AM UTC 2023 (2/6): kernel-6.4.10-100.fc37.x86_64.rpm 1.2 MB/s | 140 kB 00:00 /var/cache/dnf/updates-fd4d3d0d1c34d49a/packages/kernel-modules-extra-6.4.9-100.fc37_6.4.10-100.fc37.x86_64.drpm: md5 mismatch of result ##$ md5sum /var/cache/dnf/updates-fd4d3d0d1c34d49a/packages/kernel-modules-extra-6.4.9-100.fc37_6.4.10-100.fc37.x86_64.drpm 356ea04e06bd58db4a15c64e64432f1a /var/cache/dnf/updates-fd4d3d0d1c34d49a/packages/kernel-modules-extra-6.4.9-100.fc37_6.4.10-100.fc37.x86_64.drpm Another possible approach: install Fedora 37 in VM without internet access and then do `dnf update` (haven't tested this yet). After second download, the kernel update passes, but I don't understand why the second download via http://mirror should pass. Examining the dnf source is option. Open problem: Can this be vulnerability, possibly assuming hostile mirror or network? Also, isn't md5 deprecated and known to suck much? -- guninski https://www.guninski.com/me.html _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: https://seclists.org/fulldisclosure/
