Buffer overflow in the png_read_IDAT_data function in pngrutil.c in libpng before 1.5.21 and 1.6.x before 1.6.16 allows context-dependent attackers to execute arbitrary code via IDAT data with a large width, a different vulnerability than CVE-2014-9495.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-093178 advisory.

    Buffer overflow in the png_read_IDAT_data function in pngrutil.c in libpng before 1.5.21 and 1.6.x before     1.6.16 allows context-dependent attackers to execute arbitrary code via IDAT data with a large width, a     different vulnerability than CVE-2014-9495.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

An update of the syslinux package has been released.

According to the versions of the libpng packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Heap-based buffer overflow in the png_combine_row     function in libpng before 1.5.21 and 1.6.x before     1.6.16, when running on 64-bit systems, might allow     context-dependent attackers to execute arbitrary code     via a 'very wide interlaced' PNG image.(CVE-2014-9495)

  - Buffer overflow in the png_read_IDAT_data function in     pngrutil.c in libpng before 1.5.21 and 1.6.x before     1.6.16 allows context-dependent attackers to execute     arbitrary code via IDAT data with a large width, a     different vulnerability than     CVE-2014-9495.(CVE-2015-0973)

  - Buffer overflow in the png_set_PLTE function in libpng     before 1.0.65, 1.1.x and 1.2.x before 1.2.55, 1.3.x,     1.4.x before 1.4.18, 1.5.x before 1.5.25, and 1.6.x     before 1.6.20 allows remote attackers to cause a denial     of service (application crash) or possibly have     unspecified other impact via a small bit-depth value in     an IHDR (aka image header) chunk in a PNG image. NOTE:
    this vulnerability exists because of an incomplete fix     for CVE-2015-8126.(CVE-2015-8472)

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

The remote host is running a version of Mac OS X version 10.11.x prior to 10.11.4 and is affected by multiple vulnerabilities in the following components :

 - apache_mod_php
 - AppleRAID
 - AppleUSBNetworking
 - Bluetooth
 - Carbon
 - dyld
 - FontParser
 - HTTPProtocol
 - Intel Graphics Driver
 - IOFireWireFamily
 - IOGraphics

 - NVIDIA Graphics Drivers
 - OpenSSH
 - OpenSSL
 - Python
 - QuickTime
 - Reminders

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

The remote host is running a version of Mac OS X that is 10.9.5 or 10.10.5 and is missing Security Update 2016-002. It is, therefore, affected by multiple vulnerabilities in the following components :

  - apache_mod_php
  - Kernel
  - libxml2
  - OpenSSH
  - Python
  - Tcl

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

This update fixes the following security issues :

  - CVE-2014-9495: libpng versions heap overflow     vulnerability, that under certain circumstances could be     exploit. [bnc#912076]

  - CVE-2015-0973: A heap-based overflow was found in the     png_combine_row() function of the libpng library, when     very large interlaced images were used.[bnc#912929]

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.

This update addresses a couple of buffer overflows that might allow context-dependent attackers to execute arbitrary code via very wide PNG images.

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

libpng was updated to fix some security issues :

  - CVE-2014-9495 [bnc#912076]: Heap-buffer overflow     png_combine_row() with very wide interlaced images

  - CVE-2015-0973 [bnc#912929]: overflow in     png_read_IDAT_data

libpng is now also build with -DPNG_SAFE_LIMITS_SUPPORTED.
