An essential security update has been published for Debian addressing vulnerabilities in GnuPG related to input validation that may result in possible corruption of the keyring.
KB Sriram discovered that GnuPG, the GNU Privacy Guard did not sufficiently sanitise public keys on import, which could lead to memory and keyring corruption

Summary

The problem affects both version 1, in the 'gnupg' package, and
version two, in the 'gnupg2' package.

For the stable distribution (squeeze), this problem has been fixed in
version 1.4.10-4+squeeze1 of gnupg and version 2.0.19-2+squeeze1 of
gnupg2.
