Description Josh Bressers 2007-02-28 21:33:42 UTC
CoreLabs has reported several flaws in the way gnupg verifies signed messages. 
It is possible to construct a message with injected content and it will appear
to be valid, signed content.

This flaw is most dangerous in the way many mail programs use gnupg to verify
signed and encrypted messages.

Comment 1 Josh Bressers 2007-02-28 21:34:14 UTC
These flaws also affect RHEL2.1 and RHEL3
