Description

The XvQueryAdaptors and XvQueryEncodings functions in X.org libXv before
1.0.11 allow remote X servers to trigger out-of-bounds memory access
operations via vectors involving length specifications in received data
(CVE-2016-5407).

The XGetImage function in X.org libX11 before 1.6.4 might allow remote X
servers to gain privileges via vectors involving image type and geometry,
which triggers out-of-bounds read operations (CVE-2016-7942).

The XListFonts function in X.org libX11 before 1.6.4 might allow remote X
servers to gain privileges via vectors involving length fields, which
trigger out-of-bounds write operations (CVE-2016-7943).

Integer overflow in X.org libXfixes before 5.0.3 on 32-bit platforms might
allow remote X servers to gain privileges via a length value of INT_MAX,
which triggers the client to stop reading data and get out of sync
(CVE-2016-7944).

Multiple integer overflows in X.org libXi before 1.7.7 allow remote X
servers to cause a denial of service (out-of-bounds memory access or
infinite loop) via vectors involving length fields (CVE-2016-7945).

X.org libXi before 1.7.7 allows remote X servers to cause a denial of
service (infinite loop) via vectors involving length fields
(CVE-2016-7946).

Multiple integer overflows in X.org libXrandr before 1.5.1 allow remote X
servers to trigger out-of-bounds write operations via a crafted response
(CVE-2016-7947).

X.org libXrandr before 1.5.1 allows remote X servers to trigger
out-of-bounds write operations by leveraging mishandling of reply data
(CVE-2016-7948).

Multiple buffer overflows in the XvQueryAdaptors and XvQueryEncodings
functions in X.org libXrender before 0.9.10 allow remote X servers to
trigger out-of-bounds write operations via vectors involving length fields
(CVE-2016-7949).

The XRenderQueryFilters function in X.org libXrender before 0.9.10 allows
remote X servers to trigger out-of-bounds write operations via vectors
involving filter name lengths (CVE-2016-7950).

Multiple integer overflows in X.org libXtst before 1.2.3 allow remote X
servers to trigger out-of-bounds memory access operations by leveraging
the lack of range checks (CVE-2016-7951).

X.org libXtst before 1.2.3 allows remote X servers to cause a denial of
service (infinite loop) via a reply in the XRecordStartOfData,
XRecordEndOfData, or XRecordClientDied category without a client sequence
and with attached data (CVE-2016-7952).

Buffer underflow in X.org libXvMC before 1.0.10 allows remote X servers to
have unspecified impact via an empty string (CVE-2016-7953).
