Episode: To sign or not to sign: Practical vulnerabilities in GPG & friends (39c3)
Description: Might contain zerodays. https://gpg.fail/
From secure communications to software updates: PGP implementations such as *GnuPG* ubiquitously relied on to provide cryptographic assurances. Many applications from secure communications to software updates fundamentally rely on these utilities.
Since these have been developed for decades, one might expect mature codebases, a multitude of code audit reports, and extensive continuous testing.
When looking into various PGP-related codebases for some personal use cases, we found these expectations not met, and discovered multiple vulnerabilities in cryptographic utilities, namely in *GnuPG*, *Sequoia PGP*, *age*, and *minisign*.
The vulnerabilities have implementation bugs at their core, for...
