SUSE SLES11 Security Update : xorg-x11-libX11 (SUSE-SU-2018:2934-1)

High Nessus Plugin ID 117859


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


This update for xorg-x11-libX11 fixes the following issues :

CVE-2018-14599: The function XListExtensions was vulnerable to an
off-by-one error caused by malicious server responses, leading to DoS
or possibly unspecified other impact (bsc#1102062)

CVE-2018-14600: The function XListExtensions interpreted a variable as
signed instead of unsigned, resulting in an out-of-bounds write (of up
to 128 bytes), leading to DoS or remote code execution (bsc#1102068)

CVE-2018-14598: A malicious server could have sent a reply in which
the first string overflows, causing a variable to be set to NULL that
will be freed later on, leading to DoS (segmentation fault)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
