"A format string vulnerability exists in gnupg 1.0.5 and previous
versions which is fixed in 1.0.6. This vulnerability can be used to
invoke shell commands with privileges of the currently logged-in user.

Update :

The /usr/bin/gpg executable was installed setuid root and setgid root.
While being setuid root offers locking pages in physical memory to
avoid writing sensitive material to swap and is of benefit, being
setgid root provides no benefits and allows users to write to files
that have group root access. This update strips the setgid bit from
/usr/bin/gpg."
