Young Xiao 3aef207f90 bmp_read_rle4_data(): avoid potential infinite loop 2019-04-15 16:10:18 +08:00
Young Xiao 21399f6b7d convertbmp: detect invalid file dimensions early 
width/length dimensions read from bmp headers are not necessarily
valid. For instance they may have been maliciously set to very large
values with the intention to cause DoS (large memory allocation, stack
overflow). In these cases we want to detect the invalid size as early
as possible.

This commit introduces a counter which verifies that the number of
written bytes corresponds to the advertized width/length.

See commit 8ee335227b for details.

Fixes #1053 / CVE-2018-5727

Note: I don't consider this issue to be a security vulnerability, in
practice.
At least with gcc or clang compilers on x86_64 which generate the same
assembly code with or without that fix.

jp3d/jpwl convert: fix write stack buffer overflow
 2018-11-16 09:42:19 +01:00
ichlubna c196b23b90 openjp3d: Int overflow fixed (#1159) 
When compressing a lot of slices (starting from 44 FullHD slices with 3 8bit components in our experiments) the rate values are high enough to cause an int overflow that leads to negative lengths and wrong results. The cast happens too late.

Hugo Lefeuvre cab352e249 jp2: convert: fix null pointer dereference 
Tile components in a JP2 image might have null data pointer by defining a
zero component size (for example using large horizontal or vertical
sampling periods). This null data pointer leads to null image component
data pointer, causing crash when dereferenced without != null check in
imagetopnm.

Add != null check.

This commit addresses #1152 (CVE-2018-18088).

Stefan Weil 948332e6ed Fix some potential overflow issues (#1161) 
* Fix some potential overflow issues

Put sizeof to the beginning of the multiplication to enforce that
size_t instead of smaller integer types is used for the calculation.

This fixes warnings from LGTM:

    Multiplication result may overflow 'unsigned int'
    before it is converted to 'unsigned long'.

It also allows removing some type casts.
