Commit c4bf96bb51dd2a1b0e185374362ee136fe2c9d7f
- [MOX-002] CVE-2016-9063 / bsc#1047240 -- Detect integer overflow;
(Fixed version of existing downstream patches!)
- (SF.net) #539 Fix regression from fix to CVE-2016-0718 cutting off
longer tag names;
#25 More integer overflow detection (function poolGrow);
- [MOX-002] Detect overflow from len=INT_MAX call to XML_Parse;
- [MOX-005] #30 Use high quality entropy for hash initialization:
* arc4random_buf on BSD, systems with libbsd
(when configured with --with-libbsd), CloudABI
* RtlGenRandom on Windows XP / Server 2003 and later
* getrandom on Linux 3.17+
In a way, that's still part of CVE-2016-5300.
