Security vulnerability in h2o 2.2.4

[Pete Chown]

Hello,

The release information for h2o 2.2.5 notes that a security vulnerability was fixed; see:

https://github.com/h2o/h2o/releases/tag/v2.2.5

This release is available for Cosmic but has not been backported to Bionic. Would it be possible to do this?

The weakness is described as a buffer overflow, so it seems likely that it allows for arbitrary code execution, though details have not yet been published. CVE-2018-0608 has been assigned but is currently blank.

Many thanks,
Pete

Hi Pete!

Since the h2o package is in the universe repository, it is community maintained. This means that the security team will not be fixing the package unless a community member contributes a debdiff for sponsoring that fixes the issue.

Here is the commit that fix this in upstream:

Thanks for taking the time to report this bug and helping to make Ubuntu better. Since the package referred to in this bug is in universe or multiverse, it is community maintained. If you are able, I suggest coordinating with upstream and posting a debdiff for this issue. When a debdiff is available, members of the security team will review it and publish the package.
