[legacy] Fix buffer overflow in v0.2 and v0.4 raw literals decompression
 2019-08-21 10:10:24 -07:00
Carl Woffenden 901ea61f83 Tweaks to create a single-file decoder 
The CHECK_F macros differ slightly (but eventually do the same thing). Older GCC needs to fallback on the old-style pragma optimisation flags.

Nick Terrell 07f22d465d [legacy] Fix buffer overflow in v0.2 and v0.4 raw literals decompression 
Extends the fix in PR#1722 to v0.2 and v0.4. These aren't built into
zstd by default, and v0.5 onward are not affected.

I only add the `srcSize > BLOCKSIZE` check to v0.4 because the comments
say that it must hold, but the equivalent comment isn't present in v0.2.

Credit to OSS-Fuzz.

W. Felix Handte a42bbb4e05 Fix Buffer Overflow in Legacy (v0.3) Raw Literals Decompression 2019-08-15 14:28:30 -04:00
Yann Collet 782bfb858a fixed very minor inefficiency (nbSeq==127) 
The nbSeq "short" format (1-byte)
is compatible with any value < 128.

However, the code would cautiously only accept values < 127.
This is not an error, because the general 2-bytes format
is compatible with small values < 128.
Hence the inefficiency never triggered any warning.

Spotted by Intel's Smita Kumar.

Conrad Meyer ff6c81d90c Fix the build on GCC 4.x after 812e8f2a1 
The ancient GCC 4.x doesn't understand the "optimize" attribute until 4.4.
Fix the build on platforms with GCC 4.x < 4.4 by limiting the DONT_VECTORIZE
definition to GCC 5 and greater.

Noticed and patch proposed by Warner Losh <imp@FreeBSD.org>.

Nick Terrell e6edcfa795 [legacy] Fix bug in zstd-0.5 decoder 
The match length and literal length extra bytes could either
by 2 bytes or 3 bytes in version 0.5. All earlier verions were
always 3 bytes, and later version didn't have dumps.

The bug, introduced by commit 0fd322f812,
was triggered when the last dump was a 2-byte dump, because we didn't
separate that case from a 3-byte dump, and thought we were over-reading.

I've tested this fix with every zstd version < 1.0.0 on the buggy file,
and we are now always successfully decompressing with the right
checksum.

Fixes #1693.

* [ldm] Fix bug in overflow correction with large job size

* [zstdmt] Respect ZSTDMT_JOBSIZE_MAX (1G in 64-bit mode)

* [test] Add test that exposes the bug

Sadly the test fails on our CI because it uses too much memory, so
I had to comment it out.
