Subject: [PATCH] rar: Fix double free with over 4 billion nodes (#2598)
If a system is capable of handling 4 billion nodes in memory, a double
free could occur because of an unsigned integer overflow leading to a
realloc call with size argument of 0. Eventually, the client will
release that memory again, triggering a double free.

# This patch originally consisted of 3 hunks on the upstream:
# https://github.com/libarchive/libarchive/pull/2898/changes/e1907c5832b6489c7b4198b0825f857c93a03c10
# https://github.com/libarchive/libarchive/pull/2898/changes/d379dc0b2976b7207d1ad78f5ed3eb99a5b6d375
# but only the first hunk needs to be backported since the
# logic fix the second hunk provides does not need to be added
# as the logic is still correct in the current version of libarchive (3.3.3)
# thus the vulnerability in the code does not yet exist
#
# the third hunk of the patch is not needed either as the part of
# the code which contains the vulnerability is not yet present in this version (3.3.3)
