[PHP-DEV] Bug #3102: Buffer overflow with rfc822_date From: sherin <email protected>
Date: 01/04/00

From: sherin <email protected>

Bug description: Buffer overflow with rfc822_date

A buffer overflow occured in the function php3_imap_check in functions/imap.c while executing the following command:

rfc822_date (date);

The problem with this is that it is not checked if the returned date string is too long for the buffer. In my configuration i didn`t set up the timezone correct, so I got a somewhat large date string back.:

"Tue, 4 Jan 2000 15:42:40 +0000 (Local time zone must be set--see zic manual page)"

which was larger than the 50 chars allocated for the variable date could handle. I assume there are also other places where this problem occurs.
