Tavis Ormandy discovered a flaw in the way GnuPG verifies cryptographically signed data with inline signatures. It is possible for an attacker to add unsigned text to a signed message in such a way so that when the signed text is extracted, the unsigned text is extracted as well, appearing as if it had been signed. The Common Vulnerabilities and Exposures project assigned the name CVE-2006-0049 to this issue.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
