(Libpng: Multiple vulnerabilities)

    Multiple vulnerabilities were found in libpng:
      The png_decompress_chunk() function in pngrutil.c does not properly
        handle certain type of compressed data (CVE-2010-0205)
      A buffer overflow in pngread.c when using progressive applications
        (CVE-2010-1205)
      A memory leak in pngrutil.c when dealing with a certain type of
        chunks (CVE-2010-2249)
  
Impact :

    An attacker could exploit these vulnerabilities to cause programs linked
      against the library to crash or execute arbitrary code with the
      permissions of the user running the vulnerable program, which could be
      the root user.
  
Workaround :

    There is no known workaround at this time."
