Re: Cybersecurity issues reported for DCMTK

Hi Marco,

sorry for the late thanks - so here it comes: Thanks a lot for these details. With all the "ifs" and "ands", it is not surprising that not exploit yet exists.

Great that you fiexed it quickly anyway.

Best Regards,

Markus

Re: Cybersecurity issues reported for DCMTK

Me again. I am currently writing an impact analysis for the mentioned items. And partially, I question the conclusions made by the CISA. CVE-2022-2119 - "this could allow code execution" How that? I mean, the scenario is probably that an SOP Instance UID reading e.g. "../../../windows/system32/ws2_3...

Wow, thanks a lot for the swift response Jörg. Great that it is already solved and the impact is so limited.

Cybersecurity issues reported for DCMTK

Dear DCMTK team, I have become aware of a cybersecurity weakness report by the US government: https://www.cisa.gov/uscert/ics/advisories/icsma-22-174-01 I see that the first issue "path name injection through SOP Instance UID" has already been addressed and solved (https://support.dcmtk.org/redmine/...

CMake: pass variable DCMTK_MODULES

Dear all, I am trying to build a sub-set of the DCMTK libraries by specifying the DCMTK_MODULES variable with the CMake command. I tried different ways of passing the variable and its value to CMake. However, it either only catches the first module: cmake -D BUILD_APPS=OFF -D DCMTK_MODULES=ofstd ofl...

Re: Precompiled dcmtk-tls raises glibc error on Ubuntu (different versions)

Yes Marco, that is what I was thinking as well. But I would have expected that updating to the latest LTS version of Ubuntu would do the trick, which it did not. Unfortunately ldd does not show me any dynamically linked libraries for these executables.

Re: Precompiled dcmtk-tls raises glibc error on Ubuntu (different versions)

@Michael, Jörg: Thank you very much for sharing your experience! I really needed to solve the "root problem" urgently, which is that I need a self-contained distributable set of TLS test tools. So I gave the precompiled static binaries of the V3.6.5 release a try. They work fine on both, Ubuntu 16 a...

Precompiled dcmtk-tls raises glibc error on Ubuntu (different versions)

Dear Dcmtk-Team, for a self-contained test environment, I have downloaded the statically linked dcmtk-3.6.6 pre-compiled executables with openssl support from the download page (dcmtk-3.6.6-linux-x86_64-static-tls.tar.bz2). I first "installed" on an Ubuntu-16 virtual machine, i.e. I unpacked the bin...

Re: Problem compiling dcmtk-3.6.5 with openSSL 1.1.1i

For those who may find this helpful: My problem is now solved. Mainly, it was a stupid mistake resulting from not being much used to work with MS Visual Studio. The reason why CMake did not recognize the openssl version was apparently related to a previously built osconfig.h residing in the target d...

Problem compiling dcmtk-3.6.5 with openSSL 1.1.1i

Dear DCMTK experts, I am desperatly struggling to compile the latest dcmtk release with the latest release of openSSL for Windows. I have obtained the source code for openSSL 1.1.1i and compiled/installed it successfully (which was a struggle of its own, since the latest version of the recommended A...

Re: Decompression Bug #369 / Test data cabinet

Thank you very much Marco! I somehow missed to understand that the bug refers to *color* images where Bits Stored < Bits Allocated. I agree that this is not a very realistic scenario. Will look at the images anyway - thanks for providing them - but in fact your explanation is enough for me to assess...

Dear DCMTK team and - users, I am trying to assess the impact of known issues in DCMTK on our DCMTK based implementation. It looks fine except for Bug #369 (https://support.dcmtk.org/redmine/issues/369). I am having a hard time understanding what kind of images this bug refers to. So far I have seen...

Re: Transfersyntax and VR of pixel data

Thank you very much for all your help, Jörg!

Now that I know that TS conversion ultimately happens upon writing the dataset to a file or a socket, I have completed my testcases and everything works as expected.

---->SOLVED :D

Thanks again for the great support!
