CVE-2008-2327: Buffer Overflow
First published: Mon Aug 11 2008(Updated: )
Drew Yao of Apple Product Security reported a flaw in the LZW decoder used by libtiff to handle LZW-encoded images. Translation table used by decoding algorithm is not properly re-initialized after "code clear" code is read from the stream being decoded. When reading that code, decoder should discard previous translation table and start filling it again. Later during the processing, no longer valid table entries may be indexed by the input stream, causing libtiff to follow no longer valid pointer. This can result in crash, memory corruption and possibly allow code execution.
