Package: libarchive1
Version: 2.6.1-1
Severity: serious
Tags: patch
When using the old archive_read_open function of libarchive, it calls
libarchive_read_open2 with skipper set to NULL. But that functions
always adds a function calling this one as skipper for source stream.
Which leads to segfaults when the program requests a skip.
I'm setting severity to serious to avoid it migrating to testing, as
it makes reprepro segfault, see #516515.
Attached is a patch which fixes the issue for me.
Hochachtungsvoll,
