openSUSE Security Update : X Window System client libraries (openSUSE-2016-1420)

critical Nessus Plugin ID 95644

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

This update for X Window System client libraries fixes a class of privilege escalation issues.

A malicious X server could send specially crafted data to X clients, which allowed for triggering crashes, or privilege escalation if this relationship was untrusted or crossed user or permission level boundaries.

The following libraries have been fixed :

libX11 :

- plugged a memory leak (boo#1002991, CVE-2016-7942).

- insufficient validation of data from the X server can cause out of boundary memory read (XGetImage()) or write (XListFonts()) (boo#1002991, CVE-2016-7942).

libXi :

- Integer overflows in libXi can cause out of boundary memory access or endless loops (Denial of Service) (boo#1002998, CVE-2016-7945).

- Insufficient validation of data in libXi can cause out of boundary memory access or endless loops (Denial of Service) (boo#1002998, CVE-2016-7946).

libXrandr :

- Insufficient validation of data from the X server can cause out of boundary memory writes (boo#1003000, CVE-2016-7947, CVE-2016-7948).

Solution

Update the affected X Window System client libraries packages.
