 Mandriva Linux Security Advisory                         MDKSA-2006:136

 Package : kdegraphics
 Date    : August 1, 2006
 Affected: Corporate 3.0
 _______________________________________________________________________
 
 Problem Description:
 
 Tavis Ormandy, Google Security Team, discovered several vulnerabilites
 the libtiff image processing library. Older versions of kdegraphics use
 an embedded copy of the libtiff code, with possibly the same
 vulnerabilities:
 
 Several buffer overflows have been discovered, including a stack
 buffer overflow via TIFFFetchShortPair() in tif_dirread.c, which is
 used to read two unsigned shorts from the input file. While a bounds
 check is performed via CheckDirCount(), no action is taken on the
 result allowing a pathological tdir_count to read an arbitrary number
 of unsigned shorts onto a stack buffer. (CVE-2006-3459) 
 
 A heap overflow vulnerability was discovered in the jpeg decoder,
 where TIFFScanLineSize() is  documented to return the size in bytes
 that a subsequent call to TIFFReadScanline() would write, however the
 encoded jpeg stream may disagree with these results and overrun the
 buffer with more data than expected. (CVE-2006-3460)
 
 The NeXT RLE decoder was also vulnerable to a heap overflow
 vulnerability, where no bounds checking was performed on the result of
 certain RLE decoding operations. This was solved by ensuring the
 number of pixels written did not exceed the size of the scanline
 buffer already prepared. (CVE-2006-3462)
 
 An infinite loop was discovered in EstimateStripByteCounts(), where a
 16bit unsigned short was used to iterate over a 32bit unsigned value,
 should the unsigned int (td_nstrips) have exceeded USHORT_MAX, the
 loop would never terminate and continue forever. (CVE-2006-3463)
 
 Multiple unchecked arithmetic operations were uncovered, including a
 number of the range checking operations deisgned to ensure the offsets
 specified in tiff directories are legitimate. These  can be caused to
 wrap for extreme values, bypassing sanity checks. Additionally, a
 number of codepaths were uncovered where assertions did not hold true,
 resulting in the client application calling abort(). (CVE-2006-3464)
 
 The updated packages have been patched to correct these issues.
