From 06ae8ca5a6e452e5cb555c1a511a9df8dec6657c Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Tue, 9 Feb 2010 09:35:48 +0000 Subject: - When downloading compressed content over HTTP and the app as asked libcurl to automatically uncompress it with the CURLOPT_ENCODING option, libcurl could wrongly provide the callback with more data than what the maximum documented amount. An application could thus get tricked into badness if the maximum limit was trusted to be enforced by libcurl itself (as it is documented). This is further detailed and explained in the libcurl security advisory 20100209 at http://curl.haxx.se/docs/adv_20100209.html --- lib/content_encoding.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib') diff --git a/lib/content_encoding.c b/lib/content_encoding.c index 85362da41..b8f57d001 100644 --- a/lib/content_encoding.c +++ b/lib/content_encoding.c @@ -40,7 +40,7 @@ (doing so will reduce code size slightly). */ #define OLD_ZLIB_SUPPORT 1 -#define DSIZ 0x10000 /* buffer size for decompressed data */ +#define DSIZ CURL_MAX_WRITE_SIZE /* buffer size for decompressed data */ #define GZIP_MAGIC_0 0x1f #define GZIP_MAGIC_1 0x8b -- cgit v1.2.3
