_______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:004 http://www.mandriva.com/security/ _______________________________________________________________________ Package : pdftohtml Date : January 5, 2006 Affected: 2006.0 _______________________________________________________________________ Problem Description: Multiple heap-based buffer overflows in the DCTStream::readProgressiveSOF and DCTStream::readBaselineSOF functions in the DCT stream parsing code (Stream.cc) in xpdf 3.01 and earlier, allow user-complicit attackers to cause a denial of service (heap corruption) and possibly execute arbitrary code via a crafted PDF file with an out-of-range number of components (numComps), which is used as an array index. (CVE-2005-3191) Heap-based buffer overflow in the StreamPredictor function in Xpdf 3.01 allows remote attackers to execute arbitrary code via a PDF file with an out-of-range numComps (number of components) field. (CVE-2005-3192) Heap-based buffer overflow in the JPXStream::readCodestream function in the JPX stream parsing code (JPXStream.c) for xpdf 3.01 and earlier allows user-complicit attackers to cause a denial of service (heap corruption) and possibly execute arbitrary code via a crafted PDF file with large size values that cause insufficient memory to be allocated. (CVE-2005-3193) An additional patch re-addresses memory allocation routines in goo/gmem.c (Martin Pitt/Canonical, Dirk Mueller/KDE). In addition, Chris Evans discovered several other vulnerbilities in the xpdf code base: Out-of-bounds heap accesses with large or negative parameters to "FlateDecode" stream. (CVE-2005-3192) Out-of-bounds heap accesses with large or negative parameters to "CCITTFaxDecode" stream. (CVE-2005-3624) Infinite CPU spins in various places when stream ends unexpectedly. (CVE-2005-3625) NULL pointer crash in the "FlateDecode" stream. (CVE-2005-3626) Overflows of compInfo array in "DCTDecode" stream. (CVE-2005-3627) Possible to use index past end of array in "DCTDecode" stream. (CVE-2005-3627) Possible out-of-bounds indexing trouble in "DCTDecode" stream. (CVE-2005-3627) Pdftohtml uses an embedded copy of the xpdf code, with the same vulnerabilities. The updated packages have been patched to correct these problems. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3191 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3192 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3193 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3624 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3625 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3626 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3627 _______________________________________________________________________ Updated Packages: Mandriva Linux 2006.0: 1f14f1f733a877f14e5470107ce6eea0 2006.0/RPMS/pdftohtml-0.36-2.1.20060mdk.i586.rpm 535348b440e6a16b800b1fb00b4b8d3e 2006.0/SRPMS/pdftohtml-0.36-2.1.20060mdk.src.rpm Mandriva Linux 2006.0/X86_64: 88b1b1351cda8999e1ae2b0b813798be x86_64/2006.0/RPMS/pdftohtml-0.36-2.1.20060mdk.x86_64.rpm 535348b440e6a16b800b1fb00b4b8d3e x86_64/2006.0/SRPMS/pdftohtml-0.36-2.1.20060mdk.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
