Severity: 2/4.
Creation date: 05/10/2016.
DESCRIPTION OF THE VULNERABILITY
Several vulnerabilities were announced in X.Org libraries.
An attacker can force a read at an invalid address via libX11
XGetImage(), in order to trigger a denial of service, or to obtain
sensitive information. [severity:1/4; CVE-2016-7942]
An attacker can force a read at an invalid address via libX11
XListFonts(), in order to trigger a denial of service, or to
obtain sensitive information. [severity:1/4; CVE-2016-7943]
An attacker can generate an integer overflow via libXfixes, in
order to trigger a denial of service, and possibly to run code.
[severity:2/4; CVE-2016-7944]
An attacker can force a read at an invalid address via libXi, in
order to trigger a denial of service, or to obtain sensitive
information. [severity:1/4; CVE-2016-7945]
An attacker can generate an infinite loop via libXi, in order to
trigger a denial of service. [severity:1/4; CVE-2016-7946]
An attacker can generate an integer overflow via libXrandr, in
order to trigger a denial of service, and possibly to run code.
[severity:2/4; CVE-2016-7947]
An attacker can trigger a fatal error via libXrandr, in order to
trigger a denial of service. [severity:1/4; CVE-2016-7948]
An attacker can generate a buffer overflow via libXrender, in
order to trigger a denial of service, and possibly to run code.
[severity:2/4; CVE-2016-7949]
An attacker can generate a buffer overflow via libXrender
XRenderQueryFilters, in order to trigger a denial of service, and
possibly to run code. [severity:2/4; CVE-2016-7950]
An attacker can force a read at an invalid address via libXtst
XRecord, in order to trigger a denial of service, or to obtain
sensitive information. [severity:1/4; CVE-2016-7951]
An attacker can generate an infinite loop via libXtst XRecord, in
order to trigger a denial of service. [severity:1/4; CVE-2016-7952]
An attacker can generate a memory corruption via libXv, in order
to trigger a denial of service, and possibly to run code.
[severity:2/4; CVE-2016-5407]
An attacker can force a read at an invalid address via libXvMC, in
order to trigger a denial of service, or to obtain sensitive
information. [severity:1/4; CVE-2016-7953]
