--------------------------------------
Summary: Of-by-one error in TranscodeFromStr (with ICU)
Key: XERCESC-2020
URL: https://issues.apache.org/jira/browse/XERCESC-2020
Project: Xerces-C++
Issue Type: Bug
Components: Utilities
Affects Versions: 3.1.1
Environment: ICU, Visual C++ 2012
Reporter: Martin Raiber
The char-Array charSizes in TranscodeFromStr::transcode is initialized with
length csSize.
ICUTranscoder::transcodeFrom is called with maxChars=csSize+1.
For a fixed length encoding charSizes is set via memset(charSizes, fillSize,
maxChars); writing one character too much.
To reproduce:
xercesc::TranscodeFromStr transcoder(reinterpret_cast<const XMLByte*>("foo"),
3, "ISO-8859-15");
