Multiple integer overflow flaws which could lead to heap-based buffer overflows, as well as multiple insufficient input validation flaws, were found in Ghostscript's International Color Consortium Format library (icclib). Using specially crafted ICC profiles, an attacker could create a malicious PostScript or PDF file with embedded images which could cause Ghostscript to crash, or, potentially, execute arbitrary code when opened by the victim. (CVE-2009-0583, CVE-2009-0584)

Updated ghostscript packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3 and 4.

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

Ghostscript is a set of software that provides a PostScript interpreter, a set of C procedures (the Ghostscript library, which implements the graphics capabilities in the PostScript language) and an interpreter for Portable Document Format (PDF) files.

It was discovered that the Red Hat Security Advisory RHSA-2009:0345 did not address all possible integer overflow flaws in Ghostscript's International Color Consortium Format library (icclib). Using specially crafted ICC profiles, an attacker could create a malicious PostScript or PDF file with embedded images that could cause Ghostscript to crash or, potentially, execute arbitrary code when opened. (CVE-2009-0792)

A missing boundary check was found in Ghostscript's CCITTFax decoding filter. An attacker could create a specially crafted PostScript or PDF file that could cause Ghostscript to crash or, potentially, execute arbitrary code when opened. (CVE-2007-6725)

Users of ghostscript are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

The remote host is affected by the vulnerability described in GLSA-200903-37 (Ghostscript: User-assisted execution of arbitrary code)

    Jan Lieskovsky from the Red Hat Security Response Team discovered the     following vulnerabilities in Ghostscript's ICC Library:
    Multiple integer overflows (CVE-2009-0583).
    Multiple     insufficient bounds checks on certain variable sizes     (CVE-2009-0584).
  Impact :

    A remote attacker could entice a user to open a specially crafted     PostScript file containing images and a malicious ICC profile, possibly     resulting in the execution of arbitrary code with the privileges of the     user running the application.
  Workaround :

    There is no known workaround at this time.

It was discovered that Ghostscript contained multiple integer overflows in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0583)

It was discovered that Ghostscript did not properly perform bounds checking in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0584).

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.

Integer overflows and missing upper bounds checks in Ghostscript's ICC library potentially allowed attackers to crash Ghostscript or even cause execution of arbitrary code via specially crafted PS or PDF files (CVE-2009-0583, CVE-2009-0584).

It was discovered that Ghostscript contained a buffer underflow in its CCITTFax decoding filter. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2007-6725)

It was discovered that Ghostscript contained a buffer overflow in the BaseFont writer module. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2008-6679)

It was discovered that Ghostscript contained additional integer overflows in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript or PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0792)

Alin Rad Pop discovered that Ghostscript contained a buffer overflow in the jbig2dec library. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0196)

USN-743-1 provided updated ghostscript and gs-gpl packages to fix two security vulnerabilities. This update corrects the same vulnerabilities in the gs-esp package.

It was discovered that Ghostscript contained multiple integer overflows in its ICC color management library. If a user or automated system were tricked into opening a crafted Postscript file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program.

New ghostscript packages are available for Slackware 12.1, 12.2, and
-current to fix security issues.
