Buffer overflow in the BaseFont writer module in Ghostscript 8.62, and possibly other versions, allows remote attackers to cause a denial of service (ps2pdf crash) and possibly execute arbitrary code via a crafted Postscript file.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2009-0421 advisory.

    - Added extra checking for CVE-2009-0792 (bug #491853).
    - Applied patch to fix CVE-2009-0792 (bug #491853).

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

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

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 buffer overflow flaw and multiple missing boundary checks were found in Ghostscript. 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-2008-6679, CVE-2007-6725, CVE-2009-0196)

Several security issues have been discovered in Ghostscript, a GPL PostScript/PDF interpreter, which might lead to the execution of arbitrary code if a user processes a malformed PDF or Postscript file.

Updated ghostscript packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

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.

Red Hat would like to thank Alin Rad Pop of Secunia Research for responsibly reporting the CVE-2009-0196 flaw.

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

Multiple security vulnerabilities has been identified and fixed in ghostscript :

A buffer underflow in Ghostscript's CCITTFax decoding filter allows remote attackers to cause denial of service and possibly to execute arbitrary by using a crafted PDF file (CVE-2007-6725).

Buffer overflow in Ghostscript's BaseFont writer module allows remote attackers to cause a denial of service and possibly to execute arbitrary code via a crafted Postscript file (CVE-2008-6679).

Multiple interger overflows in Ghostsript's International Color Consortium Format Library (icclib) allows attackers to cause denial of service (heap-based buffer overflow and application crash) and possibly execute arbitrary code by using either a PostScript or PDF file with crafte embedded images (CVE-2009-0583, CVE-2009-0584).

Multiple interger overflows in Ghostsript's International Color Consortium Format Library (icclib) allows attackers to cause denial of service (heap-based buffer overflow and application crash) and possibly execute arbitrary code by using either a PostScript or PDF file with crafte embedded images. Note: this issue exists because of an incomplete fix for CVE-2009-0583 (CVE-2009-0792).

Heap-based overflow in Ghostscript's JBIG2 decoding library allows attackers to cause denial of service and possibly to execute arbitrary code by using a crafted PDF file (CVE-2009-0196).

Multiple integer overflows in JasPer 1.900.1 might allow context-dependent attackers to have an unknown impact via a crafted image file, related to integer multiplication for memory allocation (CVE-2008-3520).

Buffer overflow in the jas_stream_printf function in libjasper/base/jas_stream.c in JasPer 1.900.1 might allow context-dependent attackers to have an unknown impact via vectors related to the mif_hdr_put function and use of vsprintf (CVE-2008-3522).

Previousely the ghostscript packages were statically built against a bundled and private copy of the jasper library. This update makes ghostscript link against the shared system jasper library which makes it easier to address presumptive future security issues in the jasper library.

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers

This update provides fixes for that vulnerabilities.

Specially crafted file could cause a heap-overflow in JBIG2 decoder (CVE-2009-0196), an integer overflow in ICC library (CVE-2009-0792), a buffer overflow in BaseFont writer module (CVE-2008-6679) or crash the CCITTFax decoder. (CVE-2007-6725)

Specially crafted file could cause a heap-overflow in JBIG2 decoder (CVE-2009-0196), an integer overflow in ICC library (CVE-2009-0792), a buffer overflow in BaseFont writer module (CVE-2008-6679) or crash the CCITTFax decoder. (CVE-2007-6725)

The previous security update introduced a regression that broke some printer drives. This new update fixes that issue.

Specially crafted file could cause a heap-overflow in JBIG2 decoder (CVE-2009-0196), an integer overflow in ICC library (CVE-2009-0792), a buffer overflow in BaseFont writer module (CVE-2008-6679) or crash the CCITTFax decoder (CVE-2007-6725).

SecurityFocus reports :

Ghostscript is prone to a remote buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before copying it into a finite-sized buffer.

Exploiting this issue allows remote attackers to overwrite a sensitive memory buffer with arbitrary data, potentially allowing them to execute malicious machine code in the context of the affected application. This vulnerability may facilitate the compromise of affected computers.
