[Vorbis-dev] can we help with libvorbis release for CVE fixes?

[Ellen Johnson]

Hi Ralph,
  Thank you for your reply!  
  For context -- we consider reported CVEs as bugs even if it's in a third-party library we use (such as libvorbis).  We first determine if the CVE is something that would impact our customer workflows.  In this case because of our use of libvorbis for audio I/O, it does impact our customers so we need to resolve the CVE as soon as possible.
  In the short term until a new version is released, I'd like to patch our libvorbis 1.3.6 with the two CVE fixes that I think are on the master branch.  From the gitlab comments, I'm pretty sure CVE-2018-10392 is fixed via issue 2335, but I'm still fuzzy on whether CVE-2018-10393 is fixed via issue 2334 because of its link to duplicate issue 2330 which doesn't exist.  See https://gitlab.xiph.org/xiph/vorbis/-/issues/2334 and the comment by Monty saying it's a dup of 2330, but Pierre comments that 2330 doesn't exist so he asked if Monty can point to the fix.
  In the longer term, we'd love to talk more about how we can help move the next release along and contribute to the libvorbis project in general.
  Yes, if you can please verify that both these CVEs are fixed in master branch, I'd really appreciate it.
  Thank you!

Hi Ellen,

Thanks for your kind offer to help the release along. We have indeed been having trouble finding resources for that.

You can certainly help by testing the git master branch with your software and reporting any issues you find. Otherwise, triaging outstanding bug reports and patches is always helpful, although that's not essential for a security-based release.

I'll try to find out what the resolution on the reported CVEs was.

Cheers,
