This update fixes this issue for the 1.4 series of GnuPG. GnuPG 2.x is affected through its use of the libgcrypt11 library, a fix for which will be published in DSA 2731.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.4.10-4+squeeze2.

For the stable distribution (wheezy), this problem has been fixed in version 1.4.12-7+deb7u1.

For the unstable distribution (sid), this problem has been fixed in version 1.4.14-1.

We recommend that you upgrade your gnupg packages.");
