Package        : gnupg
Vulnerability  : several
Problem-Type   : local(remote)
Debian-specific: no
CVE ID         : CVE-2006-6169 CVE-2006-6235
Debian Bug     : 401894 401898 401914

Several remote vulnerabilities have been discovered in the GNU privacy,
a free PGP replacement, which may lead to the execution of arbitrary code.
The Common Vulnerabilities and Exposures project identifies the following


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


    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.
