Use-after-free vulnerability in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (crash) via a crafted WMF file to the (1) wmf2gd or (2) wmf2eps command.

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.

The remote host is affected by the vulnerability described in GLSA-201602-03 (libwmf: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libwmf.  Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process or cause Denial of Service.
  Workaround :

    There is no known work around at this time.

It was discovered that libwmf did not correctly process certain WMF (Windows Metafiles) with embedded BMP images. By tricking a victim into opening a specially crafted WMF file in an application using libwmf, a remote attacker could possibly use this flaw to execute arbitrary code with the privileges of the user running the application. (CVE-2015-0848 , CVE-2015-4588)

It was discovered that libwmf did not properly process certain WMF files. By tricking a victim into opening a specially crafted WMF file in an application using libwmf, a remote attacker could possibly exploit this flaw to cause a crash or execute arbitrary code with the privileges of the user running the application. (CVE-2015-4696)

It was discovered that libwmf did not properly process certain WMF files. By tricking a victim into opening a specially crafted WMF file in an application using libwmf, a remote attacker could possibly exploit this flaw to cause a crash. (CVE-2015-4695)

The gdPngReadData function in libgd 2.0.34 allows user-assisted attackers to cause a denial of service (CPU consumption) via a crafted PNG image with truncated data, which causes an infinite loop in the png_read_info function in libpng. (CVE-2007-2756)

Buffer overflow in the gdImageStringFTEx function in gdft.c in GD Graphics Library 2.0.33 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted string with a JIS encoded font. (CVE-2007-0455)

The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.x before 5.3.1, and the GD Graphics Library 2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability than CVE-2009-3293 . NOTE:
some of these details are obtained from third party information.
(CVE-2009-3546)

Mitre reports :

Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function, a different set of vulnerabilities than CVE-2004-0990.

Buffer overflow in the gdImageStringFTEx function in gdft.c in GD Graphics Library 2.0.33 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted string with a JIS encoded font.

The gdPngReadData function in libgd 2.0.34 allows user-assisted attackers to cause a denial of service (CPU consumption) via a crafted PNG image with truncated data, which causes an infinite loop in the png_read_info function in libpng.

Integer overflow in gdImageCreateTrueColor function in the GD Graphics Library (libgd) before 2.0.35 allows user-assisted remote attackers to have unspecified attack vectors and impact.

The gdImageCreateXbm function in the GD Graphics Library (libgd) before 2.0.35 allows user-assisted remote attackers to cause a denial of service (crash) via unspecified vectors involving a gdImageCreate failure.

The (a) imagearc and (b) imagefilledarc functions in GD Graphics Library (libgd) before 2.0.35 allow attackers to cause a denial of service (CPU consumption) via a large (1) start or (2) end angle degree value.

The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.x before 5.3.1, and the GD Graphics Library 2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability than CVE-2009-3293. NOTE:
some of these details are obtained from third party information.

Heap-based buffer overflow in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted BMP image.

meta.h in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted WMF file.

Use-after-free vulnerability in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (crash) via a crafted WMF file to the (1) wmf2gd or (2) wmf2eps command.

Heap-based buffer overflow in the DecodeImage function in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted 'run-length count' in an image in a WMF file.

CVE-2015-0848 heap overflow when decoding BMP images CVE-2015-4588 RLE decoding doesn't check that the 'count' fits into the image CVE-2015-4695 meta_pen_create heap buffer overflow CVE-2015-4696 wmf2gd/wmf2eps use after free

libwmf was updated to fix four security issues.

These security issues were fixed :

  - CVE-2015-4588: Heap overflow (bnc#933109).

  - CVE-2015-4696: Use after free (bnc#936062).

  - CVE-2015-4695: Heap buffer over read (bnc#936058).

  - CVE-2015-0848: Heap overflow (bnc#933109).

Fernando Munoz and Stefan Cornelius discovered that libwmf incorrectly handled certain malformed images. If a user or automated system were tricked into opening a crafted image file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program.

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

Insufficient input sanitising in libwmf, a library to process Windows metafile data, may result in denial of service or the execution of arbitrary code if a malformed WMF file is opened.

libwmf is vulnerable to two denial of service due to invalid read operations when processing specially crafted WMF files.

CVE-2015-4695

Heap buffer overread in libwmf

CVE-2015-4696

Read after free() in wmf2gd/wmf2eps

For the squeeze distribution, those issues have been fixed in libwmf 0.2.8.4-6.2+deb6u2. We recommend that you upgrade your libwmf packages.
