| Beschreibung: | Description:
The remote host is missing an update to the system
as announced in the referenced advisory.
The following package is affected: xorg-server
CVE-2008-1377
The (1) SProcRecordCreateContext and (2) SProcRecordRegisterClients
functions in the Record extension and the (3)
SProcSecurityGenerateAuthorization function in the Security extension
in the X server 1.4 in X.Org X11R7.3 allow context-dependent attackers
to execute arbitrary code via requests with crafted length values that
specify an arbitrary number of bytes to be swapped on the heap, which
triggers heap corruption.
CVE-2008-1379
Integer overflow in the fbShmPutImage function in the MIT-SHM
extension in the X server 1.4 in X.Org X11R7.3 allows
context-dependent attackers to read arbitrary process memory via
crafted values for a Pixmap width and height.
CVE-2008-2360
Integer overflow in the AllocateGlyph function in the Render extension
in the X server 1.4 in X.Org X11R7.3 allows context-dependent
attackers to execute arbitrary code via unspecified request fields
that are used to calculate a heap buffer size, which triggers a
heap-based buffer overflow.
CVE-2008-2361
Integer overflow in the ProcRenderCreateCursor function in the Render
extension in the X server 1.4 in X.Org X11R7.3 allows
context-dependent attackers to cause a denial of service (daemon
crash) via unspecified request fields that are used to calculate a
glyph buffer size, which triggers a dereference of unmapped memory.
CVE-2008-2362
Multiple integer overflows in the Render extension in the X server 1.4
in X.Org X11R7.3 allow context-dependent attackers to execute
arbitrary code via a (1) SProcRenderCreateLinearGradient, (2)
SProcRenderCreateRadialGradient, or (3)
SProcRenderCreateConicalGradient request with an invalid field
specifying the number of bytes to swap in the request data, which
triggers heap memory corruption.
Solution:
Update your system with the appropriate patches or
software upgrades.
