Several vulnerabilities in libical

[Emilio Pozuelo Monfort]

Hi,

There have been a few vulnerabilities reported against libical, and I don't see
any fixes in the repository. I found this but it went unanswered:

https://github.com/libical/libical/issues/235

The vulnerabilities are listed in:

http://www.openwall.com/lists/oss-security/2016/06/25/4

There is little information on some of them as the mozilla bugs (except for one)
are marked as private. Perhaps Brandon (Cc'ed) can open them or provide some
information.

Thanks,
Emilio
