Debian Bug     : 480133 480134 480135

Several remote vulnerabilities have been discovered in rdesktop, a
Remote Desktop Protocol client. The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2008-1801

    Remote exploitation of an integer underflow vulnerability allows
    attackers to execute arbitrary code with the privileges of the
    logged-in user.

CVE-2008-1802

    Remote exploitation of a BSS overflow vulnerability allows
    attackers to execute arbitrary code with the privileges of the
    logged-in user.

CVE-2008-1803

    Remote exploitation of an integer signedness vulnerability allows
    attackers to execute arbitrary code with the privileges of the
    logged-in user.


For the stable distribution (etch), these problems have been fixed in
version 1.5.0-1etch2.

For the unstable distribution (sid), these problems have been fixed in
version 1.5.0-4+cvs20071006.

We recommend that you upgrade your rdesktop package.
