Synopsis

The remote openSUSE host is missing a security update.

Description

This update for the 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.

libX11, libXfixes, libXi, libXrandr, libXrender, libXtst, libXv, libXvMC were fixed, specifically :

libX11 :

- CVE-2016-7942: insufficient validation of data from the X server allowed out of boundary memory read (bsc#1002991)

libXfixes :

- CVE-2016-7944: insufficient validation of data from the X server can cause an integer overflow on 32 bit architectures (bsc#1002995)

libXi :

- CVE-2016-7945, CVE-2016-7946: insufficient validation of data from the X server can cause out of boundary memory access or endless loops (Denial of Service) (bsc#1002998)

libXtst :

- CVE-2016-7951, CVE-2016-7952: insufficient validation of data from the X server can cause out of boundary memory access or endless loops (Denial of Service) (bsc#1003012)

libXv :

- CVE-2016-5407: insufficient validation of data from the X server can cause out of boundary memory and memory corruption (bsc#1003017)

libXvMC :

- CVE-2016-7953: insufficient validation of data from the X server can cause a one byte buffer read underrun (bsc#1003023)

libXrender :

- CVE-2016-7949, CVE-2016-7950: insufficient validation of data from the X server can cause out of boundary memory writes (bsc#1003002)

libXrandr :

- CVE-2016-7947, CVE-2016-7948: insufficient validation of data from the X server can cause out of boundary memory writes (bsc#1003000)

This update was imported from the SUSE:SLE-12:Update update project.
