CVE-2022-3219
First published: Thu Sep 15 2022(Updated: )
GnuPG can be made to spin on a relatively small input by (for example) crafting a public key with thousands of signatures attached, compressed down to just a few KB; see $URL and the surrounding email threads for more details and test-cases. The reporter has some proposed patches at <a href="https://dev.gnupg.org/D556">https://dev.gnupg.org/D556</a> (and in oss-security / gnupg-devel threads); mostly these flag/reject compressed packets and indeterminate-length packets in contexts where they make no sense and arguably are not within the spec (certificates, keys, detached signatures).
