There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - tlslite-ng version 0.7.3 and earlier, since commit d7b288316bca7bcdd082e6ccff5491e241305233 contains a
 CWE-354: Improper Validation of Integrity Check Value vulnerability in TLS implementation,
 tlslite/utils/constanttime.py: ct_check_cbc_mac_and_pad(); line "end_pos = data_len - 1 - mac.digest_size"
