Summary
- CVE-2014-8091 (denial of service)
X.Org X Window System, when using SUN-DES-1 (Secure RPC) authentication
credentials, does not check the return value of a malloc call, which
allows remote attackers to cause a denial of service (NULL pointer
dereference and server crash) via a crafted connection request.
- CVE-2014-8092 (arbitrary code execution)
A flaw allow remote authenticated users to cause a denial of service or
possibly execute arbitrary code via a crafted request to various
affected functions, which triggers an out-of-bounds read or write.
- CVE-2014-8093 (arbitrary code execution)
Multiple integer overflows allow remote authenticated users to cause a
denial of service or possibly execute arbitrary code via a crafted
request to various affected functions, which triggers an out-of-bounds
read or write.
- CVE-2014-8094 (arbitrary code execution)
Integer overflow in the ProcDRI2GetBuffers function in the DRI2
extension allows remote authenticated users to cause a denial of service
or possibly execute arbitrary code via a crafted request, which triggers
an out-of-bounds read or write.
- CVE-2014-8095 (arbitrary code execution)
The XInput extension allows remote authenticated users to cause a denial
of service (out-of-bounds read or write) or possibly execute arbitrary
code via a crafted length or index value to various affected functions.
- CVE-2014-8096 (arbitrary code execution)
The SProcXCMiscGetXIDList function in the XC-MISC extension allows
remote authenticated users to cause a denial of service (out-of-bounds
read or write) or possibly execute arbitrary code via a crafted length
or index value.
- CVE-2014-8097 (arbitrary code execution)
The DBE extension allows remote authenticated users to cause a denial of
service (out-of-bounds read or write) or possibly execute arbitrary code
via a crafted length or index value to various affected functions.
- CVE-2014-8098 (arbitrary code execution)
The GLX extension allows remote authenticated users to cause a denial of
service (out-of-bounds read or write) or possibly execute arbitrary code
via a crafted length or index value to various affected functions.
- CVE-2014-8099 (arbitrary code execution)
The XVideo extension allows remote authenticated users to cause a denial
of service (out-of-bounds read or write) or possibly execute arbitrary
code via a crafted length or index value to various affected function.
- CVE-2014-8100 (arbitrary code execution)
The Render extension allows remote authenticated users to cause a denial
of service (out-of-bounds read or write) or possibly execute arbitrary
code via a crafted length or index value to various affected functions.
- CVE-2014-8101 (arbitrary code execution)
The RandR extension allows remote authenticated users to cause a denial
of service (out-of-bounds read or write) or possibly execute arbitrary
code via a crafted length or index value to various affected functions.
- CVE-2014-8102 (arbitrary code execution)
The SProcXFixesSelectSelectionInput function in the XFixes extension
allows remote authenticated users to cause a denial of service
(out-of-bounds read or write) or possibly execute arbitrary code via a
crafted length value.
- CVE-2014-8103 (arbitrary code execution)
A flaw allows remote authenticated users to cause a denial of service
(out-of-bounds read or write) or possibly execute arbitrary code via a
crafted length or index value to various affected functions in the DRI3
or Present extension.
