Using the JBIG-KIT library

This text explains how to use the functions provided by the JBIG-KIT
@@ -735,19 +735,36 @@ None of the above limitations can be exceeded by a JBIG data stream
that conforms to the ITU-T T.85 application profile for the use of
JBIG1 in fax machines.
-The current implementation of the jbig.c decoder does not impose any
-limits on the image size that it will process, as long as malloc() is
-able to allocate enough heap space for the resulting bitmaps. The only
-exception is that jbg_dec_in() will return "Input data stream uses
+The maximum image size that a BIE header (BIH) can indicate is X_D =
+2^32-1 pixels wide, Y_D = 2^32-1 lines high, with P = 255 bits per
+pixel. Such an image would, in uncompressed form, require about 588
+exabytes. Once jbg_dec_in() has received the 20-byte long BIH at the
+start of the BIE, it will call malloc() to allocate enough memory to
+hold the uncompressed image planes. Users may, therefore, want to
+defend their application against excessive image-size parameters in a
+received BIH, by checking X_D, Y_D, and P against appropriate safety
+limits before handing over the BIE header to jbg_dec_in(). BIE headers
+indicating too large images might be abused for denial of service
+attacks, to exhaust the memory of a system (e.g., CVE-2017-9937). To
+manage this risk, the jbig.c decoder will now, by default, return "Not
+enough memory available" (JBG_ENOMEM) if the resulting final image
+layer would occupy more than 2 gigabytes. Users can adjust this limit
+by changing sd->maxmem right after having called jbg_dec_init(&sd).
+The actual amount of memory allocated with malloc() calls during the
+decoding process is somewhat higher (at least 25%) than the limit set
+in sd->maxmem, as the decoder requires additional heap memory that
+depends on the image dimensions.
+
+The jbg_dec_in() function will return "Input data stream uses
unimplemented JBIG features" (JBG_EIMPL | 1) if Y_D equals 0xffffffff,
which is an extreme value commonly used to encode images according to
ITU-T T.85 where the height was unknown when the BIH was emitted.
-After jbg_dec_in() received the 20-byte long BIH at the start of the
-BIE, it will malloc() to allocate enough memory to hold the requested
-image planes and layers. If you want to defend your application
-against excessive image-size parameters in a received BIH, then do
-make sure that you check X_D, Y_D, and P against appropriate safety
-limits before handing over the BIH to jbg_dec_in().
+
+All malloc(), realloc() and free() functions called by jbig.c are
+wrapped by the functions checked_malloc(), checked_realloc() and
+checked_free(). These simply call abort() when memory allocation
+fails. Developpers of embedded systems may want to replace them with
+alternative forms of exception handling.
There are two more limitations of the current implementation of the
jbig.c decoder that might cause problems with processing JBIG data
