Subject: [PATCH] Resolve call to srand, use more entropy (patch version 1.0)
|
||||
|
||||
Squashed backport against vanilla Expat 2.1.1, addressing:
|
||||
* CVE-2012-6702 -- unanticipated internal calls to srand
|
||||
* CVE-2016-5300 -- use of too little entropy
|
||||
|
||||
Since commit e3e81a6d9f0885ea02d3979151c358f314bf3d6d
|
||||
(released with Expat 2.1.0) Expat called srand by itself
|
||||
from inside generate_hash_secret_salt for an instance
|
||||
of XML_Parser if XML_SetHashSalt was either (a) not called
|
||||
for that instance or if (b) salt 0 was passed to XML_SetHashSalt
|
||||
prior to parsing. That call to srand passed (rather litle)
|
||||
entropy extracted from the current time as a seed for srand.
|
||||
|
||||
That call to srand (1) broke repeatability for code calling
|
||||
srand with a non-random seed prior to parsing with Expat,
|
||||
and (2) resulted in a rather small set of hashing salts in
|
||||
Expat in total.
|
||||
|
||||
For a short- to mid-term fix, the new approach avoids calling
|
||||
srand altogether, extracts more entropy out of the clock and
|
||||
other sources, too.
|
||||
|
||||
For a long term fix, we may want to read sizeof(long) bytes
|
||||
from a source like getrandom(..) on Linux, and from similar
|
||||
sources on other supported architectures.
