SUSE SLED12 / SLES12 Security Update : X Window System client libraries (SUSE-SU-2016:2505-1)

critical Nessus Plugin ID 94036

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

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)
