Description of the patch
This update for hylafax+ fixes the following issues: Hylafax was updated to upstream version 7.0.3. Security issues fixed: - CVE-2020-15396: Secure temporary directory creation for faxsetup, faxaddmodem, and probemodem (boo#1173521). - CVE-2020-15397: Sourcing of files into binaries from user writeable directories (boo#1173519). Non-security issues fixed: * add UseSSLFax feature in sendfax, sendfax.conf, hyla.conf, and JobControl (31 Jul 2020) * be more resilient in listening for the Phase C carrier (30 Jul 2020) * make sure to return to command mode if HDLC receive times out (29 Jul 2020) * make faxmail ignore boundaries on parts other than multiparts (29 Jul 2020) * don't attempt to write zero bytes of data to a TIFF (29 Jul 2020) * don't ever respond to CRP with CRP (28 Jul 2020) * reset frame counter when a sender retransmits PPS for a previously confirmed ECM block (26 Jul 2020) * scrutinize PPM before concluding that the sender missed our MCF (23 Jul 2020) * fix modem recovery after SSL Fax failure (22, 26 Jul 2020) * ignore echo of PPR, RTN, CRP (10, 13, 21 Jul 2020) * attempt to handle NSF/CSI/DIS in Class 1 sending Phase D (6 Jul 2020) * run scripts directly rather than invoking them via a shell for security hardening (3-5 Jul 2020) * add senderFumblesECM feature (3 Jul 2020) * add support for PIN/PIP/PRI-Q/PPS-PRI-Q signals, add senderConfusesPIN feature, and utilize PIN for rare conditions where it may be helpful (2, 6, 13-14 Jul 2020) * add senderConfusesRTN feature (25-26 Jun 2020) * add MissedPageHandling feature (24 Jun 2020) * use and handle CFR in Phase D to retransmit Phase C (16, 23 Jun 2020) * cope with hearing echo of RR, CTC during Class 1 sending (15-17 Jun 2020) * fix listening for retransmission of MPS/EOP/EOM if it was received corrupt on the first attempt (15 Jun 2020) * don't use CRP when receiving PPS/PPM as some senders think we are sending MCF (12 Jun 2020) * add BR_SSLFAX to show SSL Fax in notify and faxinfo output (1 Jun 2020) * have faxinfo put units on non-standard page dimensions (28 May 2020) * improve error messages for JobHost connection errors (22 May 2020) * fix perpetual blocking of jobs when a job preparation fails, attempt to fix similar blocking problems for bad jobs in batches, and add 'unblock' faxconfig feature (21 May 2020) * ignore TCF if we're receiving an SSL Fax (31 Jan 2020) * fixes for build on FreeBSD 12.1 (31 Jan - 3 Feb 2020) This update was imported from the openSUSE:Leap:15.2:Update update project.
