Log Message:
Security fix for CVE-2006-3082:

"parse-packet.c in GnuPG (gpg) 1.4.3 and 1.9.20, and earlier versions,
 allows remote attackers to cause a denial of service (gpg crash) and
 possibly overwrite memory via a message packet with a large length,
 which could lead to an integer overflow, as demonstrated using the
 --no-armor option."

Patch from GnuPG CVS repository.
Bump PKGREVISION.
