Subject: [PATCH] Avoid a double-free when a window size of 0 is specified
|
||||
|
||||
new_size can be 0 with a malicious or corrupted RAR archive.
|
||||
|
||||
realloc(area, 0) is equivalent to free(area), so the region would
|
||||
be free()d here and the free()d again in the cleanup function.
|
||||
|
||||
Found with a setup running AFL, afl-rb, and qsym.

Subject: [PATCH] rar: file split across multi-part archives must match
|
||||
|
||||
Fuzzing uncovered some UAF and memory overrun bugs where a file in a
|
||||
single file archive reported that it was split across multiple
|
||||
volumes. This was caused by ppmd7 operations calling
|
||||
rar_br_fillup. This would invoke rar_read_ahead, which would in some
|
||||
situations invoke archive_read_format_rar_read_header. That would
|
||||
check the new file name against the old file name, and if they didn't
|
||||
match up it would free the ppmd7 buffer and allocate a new
|
||||
one. However, because the ppmd7 decoder wasn't actually done with the
|
||||
buffer, it would continue to used the freed buffer. Both reads and
|
||||
writes to the freed region can be observed.
|
||||
|
||||
This is quite tricky to solve: once the buffer has been freed it is
|
||||
too late, as the ppmd7 decoder functions almost universally assume
|
||||
success - there's no way for ppmd_read to signal error, nor are there
|
||||
good ways for functions like Range_Normalise to propagate them. So we
|
||||
can't detect after the fact that we're in an invalid state - e.g. by
|
||||
checking rar->cursor, we have to prevent ourselves from ever ending up
|
||||
there. So, when we are in the dangerous part or rar_read_ahead that
|
||||
assumes a valid split, we set a flag force read_header to either go
|
||||
down the path for split files or bail. This means that the ppmd7
|
||||
decoder keeps a valid buffer and just runs out of data.
|
||||
|
||||
Found with a combination of AFL, afl-rb and qsym.

|
||||
|
||||
Currently, it is possible to create an archive that crashes bsdtar
|
||||
with a malformed ACL:
|
||||
|
||||
Program received signal SIGSEGV, Segmentation fault.
|
||||

$1 = 1
|
||||
(gdb) p field[n]
|
||||
$2 = {start = 0x0, end = 0x0}
|
||||
|
||||
Stop this by checking that the length is not zero before beginning
|
||||
the switch statement.
|
||||
|
||||
I am pretty sure this is the bug mentioned in the qsym paper [1],
|
||||
and I was able to replicate it with a qsym + AFL + afl-rb setup.

Subject: [PATCH] warc: consume data once read
|
||||
|
||||
The warc decoder only used read ahead, it wouldn't actually consume
|
||||
data that had previously been printed. This means that if you specify
|
||||
an invalid content length, it will just reprint the same data over
|
||||
and over and over again until it hits the desired length.
|
||||
|
||||
This means that a WARC resource with e.g.
|
||||
Content-Length: 666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666665
|
||||
but only a few hundred bytes of data, causes a quasi-infinite loop.
|
||||
|
||||
Consume data in subsequent calls to _warc_read.
|
||||

||||
Found with an AFL + afl-rb + qsym setup.

Subject: [PATCH] iso9660: Fail when expected Rockridge extensions is missing
|
||||
|
||||
A corrupted or malicious ISO9660 image can cause read_CE() to loop
|
||||
forever.
|
||||
|
||||
read_CE() calls parse_rockridge(), expecting a Rockridge extension
|
||||
to be read. However, parse_rockridge() is structured as a while
|
||||
loop starting with a sanity check, and if the sanity check fails
|
||||
before the loop has run, the function returns ARCHIVE_OK without
|
||||
advancing the position in the file. This causes read_CE() to retry
|
||||
indefinitely.
|
||||
|
||||
Make parse_rockridge() return ARCHIVE_WARN if it didn't read an
|
||||
extension. As someone with no real knowledge of the format, this
|
||||
seems more apt than ARCHIVE_FATAL, but both the call-sites escalate
|
||||
it to a fatal error immediately anyway.
|
||||
|
||||
Found with a combination of AFL, afl-rb (FairFuzz) and qsym.

Subject: [PATCH] 7zip: fix crash when parsing certain archives
|
||||
|
||||
Fuzzing with CRCs disabled revealed that a call to get_uncompressed_data()
|

would sometimes fail to return at least 'minimum' bytes. This can cause

the crc32() invocation in header_bytes to read off into invalid memory.

A specially crafted archive can use this to cause a crash.

binary will also crash.
