Buffer overflow in CHudMessage::MessageDrawScan

[tmp64]

CHudMessage::MessageDrawScan doesn't check the length of the line when filling the line buffer.

halflife/cl_dll/message.cpp

Lines 286 to 297 in c7240b9

	m_parms.lineLength = 0;
	m_parms.width = 0;
	while ( *pText && *pText != '\n' )
	{
	unsigned char c = *pText;
	line[m_parms.lineLength] = c;
	m_parms.width += gHUD.m_scrinfo.charWidths[c];
	m_parms.lineLength++;
	pText++;
	}
	pText++; // Skip LF
	line[m_parms.lineLength] = 0;

The recent compiler update enabled security checks so a text line longer than 79 characters will cause all Windows clients to crash (tmp64/BugfixedHL-Rebased#195).

This bug only affects HL, DMC, Ricochet, Opposing Force and TFC. It was fixed in CS1.6, CSCZ, Blue Shift and DOD.

Seems to happen on the AG.DLL but less aggressively than bugfixedHL.DLL Be nice to get this fixed for Half-life
