Debian: New xorg-server packages fix several vulnerabilities Print E-mail

Debian Lack of validation of the parameters of the SProcSecurityGenerateAuthorization SProcRecordCreateContext functions makes it possible for a specially crafted request to trigger the swapping of bytes outside the parameter of these requests, causing memory corruption.

Debian Security Advisory DSA-1595-1                                  Thijs Kinkhorst

Package        : xorg-server
Vulnerability  : several
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2008-1377 CVE-2008-1379 CVE-2008-2360 CVE-2008-2361

Several local vulnerabilities have been discovered in the X Window system.
The Common Vulnerabilities and Exposures project identifies the following


    Lack of validation of the parameters of the
    SProcSecurityGenerateAuthorization SProcRecordCreateContext
    functions makes it possible for a specially crafted request to trigger
    the swapping of bytes outside the parameter of these requests, causing
    memory corruption.


    An integer overflow in the validation of the parameters of the
    ShmPutImage() request makes it possible to trigger the copy of
    arbitrary server memory to a pixmap that can subsequently be read by
    the client, to read arbitrary parts of the X server memory space.


    An integer overflow may occur in the computation of the size of the
    glyph to be allocated by the AllocateGlyph() function which will cause
    less memory to be allocated than expected, leading to later heap


    An integer overflow may occur in the computation of the  size of the
    glyph to be allocated by the ProcRenderCreateCursor() function which
    will cause less memory to be allocated than expected, leading later
    to dereferencing un-mapped memory, causing a crash of the X server.


    Integer overflows can also occur in the code validating the parameters
    for the SProcRenderCreateLinearGradient, SProcRenderCreateRadialGradient
    and SProcRenderCreateConicalGradient functions, leading to memory
    corruption by swapping bytes outside of the intended request

For the stable distribution (etch), these problems have been fixed in version

For the unstable distribution (sid), these problems have been fixed in
version 2:1.4.1~git20080517-2.

We recommend that you upgrade your xorg-server package.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
