- akerl_ 10mo agoSince when are age or minisign PGP implementations?
- some_furry 10mo agoThe talk title includes "& Friends", for what it's worth.
- pornel 10mo agoThey're not, but the flaws they found are independent of PGP. Mainly invalid handling of strings in C and allowing untrusted ANSI codes in terminal output.
- pornel 10mo agoSequoia is mentioned in only one vulnerability for supporting lines much longer than gpg. gpg silently truncates and discards long base64 lines and sequoia does not. So the vulnerability is in ability to feed more data to sequoia which doesn't have the silent data loss of gpg. In all other cases they only used sequoia as a tool to build data for demonstrating gpg vulnerabilities.
- tptacek 10mo agoThe vulnerability that opens the talk, where they walk through verifying a Linux ISO's signature and hash and then boot into a malicious image, impacts both GnuPG and Sequoia.
