The remote host is missing an update to xfree86
announced via advisory DSA 1193-1.
Several vulnerabilities have been discovered in the X Window System,
which may lead to the execution of arbitrary code or denial of service.
The Common Vulnerabilities and Exposures project identifies the
following problems:
CVE-2006-3467
Chris Evan discovered an integer overflow in the code to handle
PCF fonts, which might lead to denial of service if a malformed
font is opened.
CVE-2006-3739
It was discovered that an integer overflow in the code to handle
Adobe Font Metrics might lead to the execution of arbitrary code.
CVE-2006-3740
It was discovered that an integer overflow in the code to handle
CMap and CIDFont font data might lead to the execution of arbitrary
code.
CVE-2006-4447
The XFree86 initialization code performs insufficient checking of
the return value of setuid() when dropping privileges, which might
lead to local privilege escalation.
For the stable distribution (sarge) these problems have been fixed in
version 4.3.0.dfsg.1-14sarge2. This release lacks builds for the
Motorola 680x0 architecture, which failed due to diskspace constraints
on the build host. They will be released once this problem has been
resolved.
For the unstable distribution (sid) these problems have been fixed
in version 1:1.2.2-1 of libxfont and version 1:1.0.2-9 of xorg-server.
We recommend that you upgrade your XFree86 packages.
