Fixes LZW decoding vulnerabilities described in CVE-2008-2327

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

Drew Yao of the Apple Product Security Team reported multiple uses of uninitialized values in libtiff's LZW compression algorithm decoder.
An attacker could create a carefully crafted LZW-encoded TIFF file that would cause an application linked to libtiff to crash or potentially execute arbitrary code (CVE-2008-2327).

The updated packages have been patched to prevent this issue.

A buffer underflow (CVE-2008-2327) has been fixed in libtiff.

The remote NewStart CGSL host, running version MAIN 6.02, has libtiff packages installed that are affected by multiple vulnerabilities:

  - Buffer overflow in the t2p_write_pdf_string function in tiff2pdf in libtiff 3.8.2 and earlier allows     attackers to cause a denial of service (crash) and possibly execute arbitrary code via a TIFF file with a     DocumentName tag that contains UTF-8 characters, which triggers the overflow when a character is sign     extended to an integer that produces more digits than expected in an sprintf call. (CVE-2006-2193)

  - Heap-based buffer overflow in the JPEG decoder in the TIFF library (libtiff) before 3.8.2 allows context-     dependent attackers to cause a denial of service and possibly execute arbitrary code via an encoded JPEG     stream that is longer than the scan line size (TiffScanLineSize). (CVE-2006-3460)

  - Heap-based buffer overflow in the PixarLog decoder in the TIFF library (libtiff) before 3.8.2 might allow     context-dependent attackers to execute arbitrary code via unknown vectors. (CVE-2006-3461)

  - Heap-based buffer overflow in the NeXT RLE decoder in the TIFF library (libtiff) before 3.8.2 might allow     context-dependent attackers to execute arbitrary code via unknown vectors involving decoding large RLE     images. (CVE-2006-3462)

  - The EstimateStripByteCounts function in TIFF library (libtiff) before 3.8.2 uses a 16-bit unsigned short     when iterating over an unsigned 32-bit value, which allows context-dependent attackers to cause a denial     of service via a large td_nstrips value, which triggers an infinite loop. (CVE-2006-3463)

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

The remote host is running a version of Mac OS X 10.5.x that is prior to 10.5.5. 

Mac OS X 10.5.5 contains security fixes for a number of programs.

The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2008-91:01 advisory.

    The libtiff package contains a library of functions for manipulating     TIFF (Tagged Image File Format) image format files.  TIFF is a widely     used file format for bitmapped images.  TIFF files usually end in the     .tif extension and they are often quite large.
    CVE-2008-2327 libtiff:
    use of uninitialized memory in LZW decoder. Multiple buffer underflows in the (1)  ZWDecode and (2)     LZWDecodeCompat functions in tif_lzw.c in the LZW decoder in  ibTIFF 3.8.2 and earlier allow context-     dependent attackers to execute arbitrary code via a crafted TIFF file.
    NOTE: some of these details are obtained from third party information.

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

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

The remote OracleVM system is missing necessary patches to address critical security updates :

  - Fix buffer overrun risks caused by unchecked integer     overflow (CVE-2009-2347) Resolves: #507725

  - Fix some more LZW decoding vulnerabilities     (CVE-2009-2285) Resolves: #507725

  - Update upstream URL

  - Use -fno-strict-aliasing per rpmdiff recommendation

  - Fix LZW decoding vulnerabilities (CVE-2008-2327)     Resolves: #458812

  - Remove sgi2tiff.1 and tiffsv.1, since they are for     programs we don't ship Resolves: #460120

Updated libtiff packages that fix various security issues and a bug are now available for Red Hat Enterprise Linux 4.

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

The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.

Multiple uses of uninitialized values were discovered in libtiff's Lempel-Ziv-Welch (LZW) compression algorithm decoder. An attacker could create a carefully crafted LZW-encoded TIFF file that would cause an application linked with libtiff to crash or, possibly, execute arbitrary code. (CVE-2008-2327)

Red Hat would like to thank Drew Yao of the Apple Product Security team for reporting this issue.

A buffer overflow flaw was discovered in the tiff2pdf conversion program distributed with libtiff. An attacker could create a TIFF file containing UTF-8 characters that would, when converted to PDF format, cause tiff2pdf to crash, or, possibly, execute arbitrary code.
(CVE-2006-2193)

Additionally, these updated packages fix the following bug :

* the libtiff packages included manual pages for the sgi2tiff and tiffsv commands, which are not included in these packages. These extraneous manual pages were removed.

All libtiff users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_1334 advisory.

    This advisory aggregates security fixes for the libtiff SRPM in CIQ LTS 9.6. It addresses 86 CVEs:
    CVE-2008-2327, CVE-2010-2067, CVE-2024-7006, CVE-2022-1355, CVE-2018-19210, and 81 more.

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

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

The version of Safari installed on the remote Windows host is earlier than 3.2.  Such versions are potentially affected by several issues :

  - Safari includes a version of zlib that is affected by     multiple vulnerabilities. (CVE-2005-2096)

  - A heap-based buffer overflow issue in the libxslt library     could lead to a crash or arbitrary code execution.
    (CVE-2008-1767)

  - A signedness issue in Safari's handling of JavaScript     array indices could lead to a crash or arbitrary code     execution. (CVE-2008-2303)

  - A memory corruption issue in WebCore's handling of style     sheet elements could lead to a crash or arbitrary code     execution. (CVE-2008-2317)

  - Multiple uninitialized memory access issues in libTIFF's     handling of LZW-encoded TIFF images could lead to a     crash or arbitrary code execution. (CVE-2008-2327)

  - A memory corruption issue in ImageIO's handling of TIFF     images could lead to a crash or arbitrary code     execution. (CVE-2008-2332).

  - A memory corruption issue in ImageIO's handling of     embedded ICC profiles in JPEG images could lead to a     crash or arbitrary code execution. (CVE-2008-3608)

  - A heap-based buffer overflow in CoreGraphics' handling     of color spaces could lead to a crash or arbitrary code     execution. (CVE-2008-3623)

  - A buffer overflow in the handling of images with an     embedded ICC profile could lead to a crash or arbitrary     code execution. (CVE-2008-3642)

  - Disabling autocomplete on a form field may not prevent     the data in the field from being stored in the browser     page cache. (CVE-2008-3644)

  - WebKit's plug-in interface does not block plug-ins from     launching local URLs, which could allow a remote     attacker to launch local files in Safari and lead to the     disclosure of sensitive information. (CVE-2008-4216)
