tag_insight = "Several local vulnerabilities have been discovered in the X Window system.
The Common Vulnerabilities and Exposures project identifies the following
problems:
CVE-2008-1377
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.
CVE-2008-1379
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.
CVE-2008-2360
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
overflow.
CVE-2008-2361
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.
CVE-2008-2362
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
parameters.
For the stable distribution (etch), these problems have been fixed in version
2:1.1.1-21etch5.
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.";
