bz2.BZ2Decompressor objects could be reused after a decompression error.
If an application caught the resulting OSError and retried with the same
decompressor, crafted input could cause the decompressor to resume from an
invalid internal state and perform out-of-bounds writes to a stack buffer.
This could crash the process when processing untrusted data.
This CVE has a CVSS 4.0 score of 8.2. The patch (5755d0f08394) is
referenced in the CVEList database.

When using the "tarfile" module with a file opened in "streaming mode"
(mode="r|") the tarfile module did not properly handle EOF, making archive
parsing take exponentially longer.

tarfile.extractall() with the 'data' or 'tar' filter could be bypassed
by a crafted archive where a hardlink references a symlink stored at a
deeper name than the hardlink itself.

Makes the exclusion list a bit more readable, avoiding very long sed
expression lines.
[Kris Gavvala]:
this commit was modified to fit scarthgap. the original commit expects
to skip test_timerfd_TFD_TIMER_ABSTIME, test_date_locale2 and test_null_dlsym.
These tests were not being skipped on scarthgap so were removed from the
backport.
