io-tga.c in gdk-pixbuf before 2.32.0 uses heap memory after its allocation failed, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) and possibly execute arbitrary code via a crafted Truevision TGA (TARGA) file.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - gdk-pixbuf: Integer overflows in various pixops functions (CVE-2015-8875)

  - io-tga.c in gdk-pixbuf before 2.32.0 uses heap memory after its allocation failed, which allows remote     attackers to cause a denial of service (heap-based buffer overflow and application crash) and possibly     execute arbitrary code via a crafted Truevision TGA (TARGA) file. (CVE-2015-7673)

  - Integer overflow in the pixops_scale_nearest function in pixops/pixops.c in gdk-pixbuf before 2.32.1     allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary     code via a crafted GIF image file, which triggers a heap-based buffer overflow. (CVE-2015-7674)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - gdk-pixbuf: GIF loader buffer overflow when initializing decompression tables (CVE-2011-2897)

  - io-tga.c in gdk-pixbuf before 2.32.0 uses heap memory after its allocation failed, which allows remote     attackers to cause a denial of service (heap-based buffer overflow and application crash) and possibly     execute arbitrary code via a crafted Truevision TGA (TARGA) file. (CVE-2015-7673)

This update for gdk-pixbuf fixes the following issues :

  - CVE-2015-7552: Fixed various overflows in image handling     (boo#958963).

  - CVE-2015-7673: Fixed an overflow and DoS with a TGA file     (boo#948790).

  - CVE-2015-7674: Fixed overflow when scaling a gif     (boo#948791).

Gustavo Grieco discovered different security issues in Gtk+2.0's gdk-pixbuf.

CVE-2015-4491

Heap overflow when processing BMP images which may allow to execute of arbitrary code via malformed images.

CVE-2015-7673

Heap overflow when processing TGA images which may allow execute arbitrary code or denial of service (process crash) via malformed images.

CVE-2015-7674

Integer overflow when processing GIF images which may allow to execute arbitrary code or denial of service (process crash) via malformed image.

For Debian 6 'Squeeze', these issues have been fixed in gtk+2.0 version 2.20.1-2+deb6u2. We recommend you to upgrade your gtk+2.0 packages.

The gdk pixbuf library was updated to fix three security issues.

These security issues were fixed :

  - CVE-2015-7673: Fix some more overflows scaling a gif     (bsc#948791)

  - CVE-2015-4491: Check for overflow before allocating     memory when scaling (bsc#942801)

  - CVE-2015-7673: Fix an overflow and DoS when scaling TGA     files (bsc#948790).

  - CVE-2015-7674: Fix overflow when scaling GIF     files(bsc#948791).

The remote host is affected by the vulnerability described in GLSA-201512-05 (gdk-pixbuf: Multiple Vulnerabilities)

    Three heap-based buffer overflow vulnerabilities have been discovered in       gdk-pixbuf. Please review the CVE identifiers referenced below for       details.
  Impact :

    A remote attacker could entice a user to open a specially crafted image       file with an application linked against gdk-pixbuf, possibly resulting in       execution of arbitrary code with the privileges of the process or a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Several vulnerabilities have been discovered in gdk-pixbuf, a toolkit for image loading and pixel buffer manipulation. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2015-7673     Gustavo Grieco discovered a heap overflow in the     processing of TGA images which may result in the     execution of arbitrary code or denial of service     (process crash) if a malformed image is opened.

  - CVE-2015-7674     Gustavo Grieco discovered an integer overflow flaw in     the processing of GIF images which may result in the     execution of arbitrary code or denial of service     (process crash) if a malformed image is opened.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2767-1 advisory.

    Gustavo Grieco discovered that the GDK-PixBuf library did not properly handle scaling tga image files,     leading to a heap overflow. If a user or automated system were tricked into opening a tga image file, a     remote attacker could use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or     possibly execute arbitrary code. (CVE-2015-7673)

    Gustavo Grieco discovered that the GDK-PixBuf library contained an integer overflow when handling certain     GIF images. If a user or automated system were tricked into opening a GIF image file, a remote attacker     could use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2015-7674)

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

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

reports :

We found a heap overflow and a DoS in the gdk-pixbuf implementation triggered by the scaling of tga file.

We found a heap overflow in the gdk-pixbuf implementation triggered by the scaling of gif file.
