Mandriva Linux Security Advisory MDKSA-2006:136
http://www.mandriva.com/security/
_______________________________________________________________________

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.
