Multiple integer overflows in (1) filter/image-png.c and (2) filter/image-zoom.c in CUPS 1.3 allow attackers to cause a denial of service (crash) and trigger memory corruption, as demonstrated via a crafted PNG image.

From Red Hat Security Advisory 2008:1028 :

Updated cups packages that fix a security issue are now available for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The Common UNIX(r) Printing System (CUPS) provides a portable printing layer for UNIX operating systems.

An integer overflow flaw, leading to a heap buffer overflow, was discovered in the Portable Network Graphics (PNG) decoding routines used by the CUPS image-converting filters, 'imagetops' and 'imagetoraster'. An attacker could create a malicious PNG file that could, potentially, execute arbitrary code as the 'lp' user if the file was printed. (CVE-2008-5286)

CUPS users should upgrade to these updated packages, which contain a backported patch to correct this issue.

An integer overflow flaw leading to a heap buffer overflow was discovered in the Portable Network Graphics (PNG) decoding routines used by the CUPS image converting filters 'imagetops' and 'imagetoraster'. An attacker could create a malicious PNG file that could possibly execute arbitrary code as the 'lp' user if the file was printed. (CVE-2008-1722)

All CUPS users are advised to upgrade to these updated packages, which contain backported patch to resolve this issue.

An attacker could create a malicious PNG file that could possibly execute arbitrary code as the 'lp' user if the file was printed. (CVE-2008-1722)

It was discovered that the SGI image filter in CUPS did not perform proper bounds checking. If a user or automated system were tricked into opening a crafted SGI image, an attacker could cause a denial of service. (CVE-2008-3639)

It was discovered that the texttops filter in CUPS did not properly validate page metrics. If a user or automated system were tricked into opening a crafted text file, an attacker could cause a denial of service. (CVE-2008-3640)

It was discovered that the HP-GL filter in CUPS did not properly check for invalid pen parameters. If a user or automated system were tricked into opening a crafted HP-GL or HP-GL/2 file, a remote attacker could cause a denial of service or execute arbitrary code with user privileges. In Ubuntu 7.10 and 8.04 LTS, attackers would be isolated by the AppArmor CUPS profile. (CVE-2008-3641)

NOTE: The previous update for CUPS on Ubuntu 6.06 LTS did not have the the fix for CVE-2008-1722 applied. This update includes fixes for the problem. We apologize for the inconvenience.

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.

Thomas Pollet discovered an integer overflow vulnerability in the PNG image handling filter in CUPS. This could allow a malicious user to execute arbitrary code with the privileges of the user running CUPS, or cause a denial of service by sending a specially crafted PNG image to the print server (CVE-2008-1722).

The updated packages have been patched to correct this issue.

CUPS users should upgrade to these updated packages, which contain a backported patch to correct this issue.

Several remote vulnerabilities have been discovered in the Common Unix Printing System (CUPS). The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2008-0053     Buffer overflows in the HP-GL input filter allowed to     possibly run arbitrary code through crafted HP-GL files.

  - CVE-2008-1373     Buffer overflow in the GIF filter allowed to possibly     run arbitrary code through crafted GIF files.

  - CVE-2008-1722     Integer overflows in the PNG filter allowed to possibly     run arbitrary code through crafted PNG files.

According to its banner, the version of CUPS installed on the remote host is affected by an integer overflow.  Using a specially crafted PNG file with overly long width and height fields, a remote attacker can leverage this issue to crash the affected service and may allow execution of arbitrary code.

Thomas Pollet discovered that CUPS did not properly validate the size of PNG images. A local attacker, and a remote attacker if printer sharing is enabled, could send a crafted file and cause a denial of service or possibly execute arbitrary code as the non-root user in Ubuntu 6.06 LTS and 7.04. In Ubuntu 7.10, attackers would be isolated by the AppArmor CUPS profile. (CVE-2008-1722).

The remote host is affected by the vulnerability described in GLSA-200804-23 (CUPS: Integer overflow vulnerability)

    Thomas Pollet reported a possible integer overflow vulnerability in the     PNG image handling in the file filter/image-png.c.
  Impact :

    A malicious user might be able to execute arbitrary code with the     privileges of the user running CUPS (usually lp), or cause a Denial of     Service by sending a specially crafted PNG image to the print server.
    The vulnerability is exploitable via the network if CUPS is sharing     printers remotely.
  Workaround :

    There is no known workaround at this time.
