Description Josh Bressers 2008-05-28 19:30:57 UTC

+++ This bug was initially created as a clone of Bug #445408 +++

iDefense reported several flaws in the X.org Render extension.  The iDefense
advisory states:

    Multiple vulnerabilities are present in the Render extension in the
    code responsible for reading in client requests. The following
    function contain the vulnerability:

    AllocateGlyph()

    In each case, values are taken from the client request and used in
    arithmetic operations that calculate the size of dynamic buffers. These
    calculations can overflow, which results in undersized buffers being
    allocated. The allocated buffers are then overflowed with data from the
    client request.
