The gdImageCreate function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to cause a denial of service (system hang) via an oversized image.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The gdImageCreate function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to     cause a denial of service (system hang) via an oversized image. (CVE-2016-9317)

Note that Nessus relies on the presence of the package as reported by the vendor.

New libwmf packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, 14.2, and -current to fix security issues.

New gd packages are available for Slackware 14.2 and -current to fix security issues.

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

  - Heap-based buffer overflow in the horizontalDifference8     function in tif_pixarlog.c in LibTIFF 4.0.6 and earlier     allows remote attackers to cause a denial of service     (crash) or execute arbitrary code via a crafted TIFF     image to tiffcp.(CVE-2016-8670)

Multiple vulnerabilities have been discovered in libgd2, a library for programmatic graphics creation and manipulation, which may result in denial of service or potentially the execution of arbitrary code if a malformed file is processed.

Multiple security issues have been found in the GD Graphics Library.
They may lead to the execution of arbitrary code or causing application crash.

CVE-2016-9317

Signed integer overflow in gd_io.c

CVE-2016-10167

Improper handling of issing image data can cause crash

CVE-2016-10168

GD2 stores the number of horizontal and vertical chunks as words (i.e.
2 byte unsigned). These values are multiplied and assigned to an int when reading the image, what can cause integer overflows.

For Debian 7 'Wheezy', these problems have been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u8.

We recommend that you upgrade your libgd2 packages.
