                  Mandrakelinux Security Update Advisory
  _______________________________________________________________________

  Package name:           wxGTK2
  Advisory ID:            MDKSA-2005:002
  Date:                   January 6th, 2005

  Affected versions:	 10.0, 10.1
  ______________________________________________________________________

  Problem Description:

  Several vulnerabilities have been discovered in the libtiff package;
  wxGTK2 uses a libtiff code tree, so it may have the same
  vulnerabilities:

  iDefense reported the possibility of remote exploitation of an integer
  overflow in libtiff that may allow for the execution of arbitrary code.

  The overflow occurs in the parsing of TIFF files set with the
  STRIPOFFSETS flag.

  iDefense also reported a heap-based buffer overflow vulnerability
  within the LibTIFF package could allow attackers to execute arbitrary
  code. (CAN-2004-1308)

  The vulnerability specifically exists due to insufficient validation of
  user-supplied data when calculating the size of a directory entry.

  The updated packages are patched to protect against these
  vulnerabilities.
