- CUPS 2.1 - security updates
Improves IPP Everywhere support, including a new dynamic IPP
Everywhere driver. The new release also adds advanced logging on
systems using ASL or journald and adds new security features to
minimize exposure - security updates
- Improved speed of ppdMarkDefaults for complex/large PPDs
(<rdar://problem/15146999>)
- The IPP backend now stops sending print data if the printer
indicates the job has been aborted or canceled
(<rdar://problem/17837631>)
- The IPP backend now sends the job-pages-per-set attribute when
printing multiple copy jobs with finishings
(<rdar://problem/16792757>)
- The IPP backend now updates the cupsMandatory values when the
printer configuration changes (<rdar://problem/18126570>)
- No longer install banner files since third-party banner filters now
supply their own (STR #4518)
- Added support for EXPECT-ALL directive in ipptool test files (STR
#4469)
- Added support for WITH-VALUE-FROM predicate in ipptool test files
(STR #4470)
- The scheduler no longer listens on the loopback interface unless the
web interface or printer sharing are enabled
(<rdar://problem/9136448>)
- Added a PPD generator for IPP Everywhere printers (STR #4258)
- Now install "default" versions of more configuration files
(<rdar://problem/19024491>)
- The cupstestppd program did not handle "maxsize(nnn)" entries in
cupsFilter/cupsFilter2 values (<rdar://problem/18974858>)
- The scheduler now checks the return value of rename() calls (STR
#4589)
- The scheduler now validates ErrorPolicy values in config files (STR
#4591)
- Long cookies caused the web interface to stop working (STR #4619)
- Added SSLOptions values to allow Diffie-Hellman key exchange and
disable TLS/1.0 support.
- Updated the scheduler to support more IPP Everywhere attributes (STR
#4630)
- The scheduler now supports advanced ASL and journald logging when
"syslog" output is configured (STR #4474)
- The scheduler now supports logging to stderr when running in the
foreground (STR #4505)
- CUPS Filters v1.0.71 release on 2 July 2015 (Till)
- texttopdf: The Page allocation is moved into textcommon.c, where it
does all the necessary checking: lower-bounds for CVE-2015-3258 and
upper-bounds for CVE-2015-3279 due to integer overflows for the
calloc() call initialising Page[0] and the memset() call in
texttopdf.c's WritePage() function zeroing the entire array. Thanks
to Tim Waugh from Red Hat for the patch.
- texttopdf: Upper-bounds checking (CVE-2015-3279).
- CUPS Filters v1.0.70 release on 26 June 2015 (Till)
- texttopdf: Fixed buffer overflow on size allocation of texttopdf
when working with extremely small line sizes, which causes the size
calculation to result in 0 (CVE-2015-3258, thanks to Stefan
Cornelius fro Red Hat for the patch).
- cups-browsed: leak fixes
- cups-browsed: Further BrowseAllow fixing
- cups-browsed: BrowsePoll is an array of pointers, not structures,
so allocate room for the pointers
- cups-browsed: Prevent NULL dereference when handling BrowseAllow
- cups-browsed: Use memory deallocation function corresponding to
allocation function used
- cups-browsed: Fixes for glib source handling (Red Hat bug #1228555)
- foomatic-rip: Allow using another shell than /bin/bash using the
"--with-shell=..." option for "./configure". Thanks to Leonardo
Taccari for the patch (Bug #1288).
- CUPS Filters v1.0.69 release on 10 June 2015 (Till)
- cups-browsed: When generating a PPD for an auto-discovered IPP
network printer, create a "ColorModel" option only if valid
choices are reported for it by the IPP printer.
- cups-browsed: Updated PPD file generator for auto-generated queues
for IPP network printers from the CUPS 2.1.x upstream code, so that
floating-point numbers are written in a locale-neutral way
(CUPS STR #4579).
- cups-browsed: When checking whether a queue name already exists
as a locally defined queue, do case-insensitive comparing as for
CUPS printer names are case-insensitive. This assures that
already existing queues do never get overwritten.
- cups-browsed: Added "IPPPrinterQueueType Auto/PPD/NoPPD" directive
to cups-browsed.conf to allow controlling how cups-browsed
creates queues fr native IPP network printers: with PPD, with
System V interface script, or selecting automatically.
- pdftopdf: Center Landscape-oriented jobs correctly on the page
if the "fitplot" or "number-up" options are used (Bug #1284).
- pstopdf: Removed "-dUseCIEColor" from the Ghostscript command line.
In modern Ghostscript versions (9.11 and newer) it is recommended to
not use it with the pdfwrite and ps2write output devices any more.
- imagetopdf: Corrections in PDF output: Let evince display the PDF
with the correct size including margins and let ghostscript not
complain about an invalid xref entry.
- cups-browsed: Do not add options to the System V interface script
which calls sys5ippprinter but set the options as defaults for the
CUPS queue in printers.conf.
- cups-browsed: When auto-generating a PPD-less print queue for an
IPP network printer, determine default page size, unprintable
margins, and color space from the printer via an IPP request.
- imagetopdf: Debug logging should be only controlled by the LogLevel
of CUPS, not by an awkward build time switch.
- cups-browsed: Determine from the TXT records of the Bonjour
broadcast of an IPP network printer whether it has color and duplex
capabilities and if yes, let auto-generated PPD-less print queues
use appropriate command line options to make use of these
capabilities.
- imagetopdf: Make this filter also work with auto-generated PPD-less
print queues for IPP network printers.
- sys5ippprinter: Renamed pdftoippprinter to reflect that it is
once a System 5 interface script and second does not accept only
PDF as input.
- pdftoippprinter: Support also PWG Raster and JPEG as input formats
so that an auto-generated, PPD-less queue for an IPP printer
emulates an IPP Everywhere printer.
- GSoC did not accept Linux Foundation as a mentor for 2015 - many *new* organizations were accepted instead - OP should consider soon GSoC 2016 projects
