CVE-2006-6169

Werner Koch discovered that a buffer overflow in a sanitising function may lead to execution of arbitrary code when running gnupg interactively.

CVE-2006-6235

Tavis Ormandy discovered that parsing a carefully crafted OpenPGP packet may lead to the execution of arbitrary code, as a function pointer of an internal structure may be controlled through the decryption routines.

For the stable distribution (sarge) these problems have been fixed in version 1.4.1-1.sarge6.

For the upcoming stable distribution (etch) these problems have been fixed in version 1.4.6-1.

For the unstable distribution (sid) these problems have been fixed in version 1.4.6-1.

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