SUSE-SA:2006:014: gpg

Vulnerability Assessment Summary
Check for the version of the gpg package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory SUSE-SA:2006:014 (gpg).

The GNU Privacy Guard (GPG) permits crafting a message which could
check out correct using '--verify', but would extract a different,
potentially malicious content when using '-o --batch'.

The reason for this is that a .gpg or .asc file can contain multiple
plain text and signature streams and the handling of these streams was
only possible when correctly following the gpg state.

The gpg '--verify' option has been changed to be way more strict than
before and fail on files with multiple signatures/blocks to mitigate
the problem of doing the common --verify checks and -o extraction.

This problem could be used by a possible hacker to remotely execute code
by using handcrafted YaST Online Patch files put onto a compromised
YOU mirror server and waiting for the user to run YOU.

This problem is tracked by the Mitre CVE ID CVE-2006-0049.

This is a different issue than the gpg signature checking problem for
