Inserting text segments into an otherwise signed message could be exploited to forge the content of signed messages. This update prevents such attacks, the old behaviour can still be activated by passing the --allow-multiple-messages option.

For the stable distribution (sarge) these problems have been fixed in version 1.4.1-1.sarge7.

For the upcoming stable distribution (etch) these problems have been fixed in version 1.4.6-2.

For the unstable distribution (sid) these problems have been fixed in version 1.4.6-2.

We recommend that you upgrade your gnupg packages.");
