Package        : vnc4
Vulnerability  : integer overflow
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2008-4770
Debian Bug     : 513531

It was discovered that xvnc4viewer, a virtual network computing client
software for X, is prone to an integer overflow via a malicious
encoding value that could lead to arbitrary code execution.

For the stable distribution (etch) this problem has been fixed in
version 4.1.1+X4.3.0-21+etch1.

For the unstable (sid) distribution this problem has been fixed in
version 4.1.1+X4.3.0-31.

For the testing (lenny) distribution this problem will be fixed soon.

We recommend that you upgrade your vnc4 packages.
