Summary: Using xampp PCRE can crash apache connection
Product: PCRE
Version: 7.8
Platform: Other
OS/Version: Windows
Status: NEW
Severity: bug
Priority: medium
Component: Code
AssignedTo: ph10@???
ReportedBy: david.gausmann@???
CC: pcre-dev@???
Hello,
I'm using PCRE to evaluate VBS source codes.
To do this I use the current xampp version (1.7.1 / win32).
During the evaluation process I've modified a regular expression.
After that my browser told me "the server has reset the connection".
The code is the following:
$sContent = 'Call ABCDEFGHJIKLMNOPQRSTUVWXYZ("Lorem Ipsum dolor sit amet,
consectetuer elitr\'" & VARIABLE & "\'" & vbCRLF &
vbCRLF & "Lorem
ipsum dolor sit amet conset" & vbCRLF &
vbCRLF & "Lorem ipsum dolor sit
amet consectetuer sadipscing.")';
echo preg_match('/^(?:[^"]|"(?:[^"]|"")*")*(?:var_alloc)\s*\(?\s*"[^"]+".*$/i',
$sContent);
As you can see the string (which shall be evaluated) is very long.
I found out that error depends on three things:
1. The length of the evaluation string
2. The |"" in the pattern (which is wrong for VBS evaluation, but it was a
test)
3. The "\'" in the evaluation string
If the pattern whould be wrong then only a php error should occur.
An other interesting fact is that the php script works fine if I execute the
script with the php.exe directly.
Hence the error depends on the combination apache - php - pcre
Kind Regards
