MDKSA-2006:008: koffice |

Check for the version of the koffice package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory MDKSA-2006:008 (koffice). 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, permit 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 permits 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 permits 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 vulnerabilities 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) Koffice uses an embedded copy of the xpdf code, with the same vulnerabilities. The updated packages have been patched to correct these problems.
