Ubuntu 4.10 : xpdf vulnerabilities (USN-14-1)

Markus Meissner discovered even more integer overflow vulnerabilities in xpdf, a viewer for PDF files. These integer overflows can eventually lead to buffer overflows. The Common UNIX Printing System CUPS uses the same code to print PDF files; tetex-bin uses the code to generate PDF output and...

Ubuntu 4.10 : xpdf vulnerabilities (USN-2-1)

Chris Evans discovered several integer overflow vulnerabilities in xpdf, a viewer for PDF files. The Common UNIX Printing System CUPS also uses the same code to print PDF files. In either case, these vulnerabilities could be exploited by an attacker by providing a specially crafted PDF file which...

Ubuntu 4.10 : cupsys vulnerabilities (USN-50-1)

CAN-2004-1125 : The recent USN-48-1 fixed a buffer overflow in xpdf. Since CUPS contains xpdf code to convert incoming PDF files to the PostScript format, this vulnerability applies to cups as well. In this case it could even lead to privilege escalation: if an attacker submitted a malicious PDF...

Ubuntu 4.10 / 5.04 : tiff vulnerability (USN-156-1)

Wouter Hanegraaff discovered that the TIFF library did not sufficiently validate the 'YCbCr subsampling' value in TIFF image headers. Decoding a malicious image with a zero value resulted in an arithmetic exception, which caused the program that uses the TIFF library to crash. This leads to a...

SUSE-SA:2006:001: xpdf,kpdf,gpdf,kword

The remote host is missing the patch for the advisory SUSE-SA:2006:001 xpdf,kpdf,gpdf,kword. 'infamous41md', Chris Evans and Dirk Mueller discovered multiple places in xpdf code where integer variables are insufficiently checked for range or overflow. Specially crafted PDF files could lead to...

Ubuntu 4.10 / 5.04 : tiff vulnerability (USN-130-1)

Tavis Ormandy discovered a buffer overflow in the TIFF library. A malicious image with an invalid 'bits per sample' number could be constructed which, when decoded, would have resulted in execution of arbitrary code with the privileges of the process using the library. Since this library is used ...

Ubuntu 4.10 : xpdf, cupsys vulnerabilities (USN-64-1)

A buffer overflow has been found in the xpdf viewer. An insufficient input validation of the encryption key length could be exploited by an attacker providing a specially crafted PDF file which, when processed by xpdf, could result in abnormal program termination or the execution of attacker...

Ubuntu 4.10 : tiff vulnerability (USN-46-1)

A buffer overflow was discovered in the TIFF library. A TIFF file includes a value indicating the number of 'directory entry' header fields contained in the file. If this value is -1, an invalid memory allocation was performed. A malicious image could be constructed which, when decoded, would hav...

RHEL 3 / 4 : cups (RHSA-2006:0163)

Updated CUPS packages that fix multiple security issues are now available for Red Hat Enterprise Linux. This update has been rated as having important security impact by the Red Hat Security Response Team. The Common UNIX Printing System CUPS provides a portable printing layer for UNIXR operating...

Fedora Core 3 : gpdf-2.8.2-7.2 (2006-025)

Chris Evans discovered several flaws in the way CUPS processes PDF files. An attacker could construct a carefully crafted PDF file that could cause CUPS to crash or possibly execute arbitrary code when opened. The Common Vulnerabilities and Exposures project assigned the names CVE-2005-3624,...

Ubuntu 4.10 / 5.04 : xpdf vulnerability (USN-163-1)

xpdf and kpdf did not sufficiently verify the validity of the 'loca' table in PDF files, a table that contains glyph description information for embedded TrueType fonts. After detecting the broken table, xpdf attempted to reconstruct the information in it, which caused the generation of a huge...

cups security update

CentOS Errata and Security Advisory CESA-2006:0163 Updated CUPS packages that fix multiple security issues are now available for Red Hat Enterprise Linux. This update has been rated as having important security impact by the Red Hat Security Response Team. The Common UNIX Printing System CUPS...

Fedora Core 3 2005-000: cups

The remote host is missing the patch for the advisory FEDORA-2005-000 cups. The Common UNIX Printing System provides a portable printing layer for UNIXr operating systems. It has been developed by Easy Software Products to promote a standard printing solution for all UNIX vendors and users. CUPS...

CVE-2005-3625

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service infinite loop via streams that end prematurely, as demonstrated using the 1 CCITTFaxDecode and 2 DCTDecode streams, aka "Infinite CPU spins."...

CVE-2005-3625

CVE-2005-3625 is confirmed to affect Xpdf and related tools (gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, etc.). The issue is a denial-of-service in PDF stream handling where streams that end prematurely can cause an infinite loop, demonstrated for the CCITTFaxDecode and DCTDecode s...

CVE-2005-3627

CVE-2005-3627 is a vulnerability in Xpdf (Stream.cc) affecting multiple products using Xpdf code paths (e.g., gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor). The issue arises in DCTDecode stream handling: (1) an unchecked large number of components value in DCTStream::readBaselineSOF/...

CVE-2005-3624

CVE-2005-3624 affects multiple PDF tools (xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, etc.). The issue is in CCITTFaxDecode handling in Stream.cc, where negative or very large integers can trigger integer overflows/underflows, leading to heap corruption. The documented impact...

USN-236-1: xpdf vulnerabilities

Chris Evans discovered several integer overflows in the XPDF code, which is present in xpdf, the Poppler library, and tetex-bin. By tricking an user into opening a specially crafted PDF file, an attacker could exploit this to execute arbitrary code with the privileges of the application that...

CVE-2005-3627

Stream.cc in Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to modify memory and possibly execute arbitrary code via a DCTDecode stream with 1 a large "number of components" value that is not checked by...

CVE-2005-3628

Buffer overflow in the JBIG2Bitmap::JBIG2Bitmap function in JBIG2Stream.cc in Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to modify memory and possibly execute arbitrary code via unknown attack vectors...
