Issue 364511: Buffer overflow vulnerability in glibc
6 people starred this issue and may be notified of changes. Back to list
 
Project Member Reported by infe...@chromium.org, Apr 17, 2014
From Kostya::

we've got ASan detecting what looks like a vulnerability in glibc,
8-byte heap buffer overflow with user-controlled data. It was fixed a
year ago, but still present in goobuntu.

What should we do about that? Announcing it in a google-wide readable
buganizer issue sounds wrong...

ASan report:
http://b.corp.google.com/issue?id=14129807

We should uptake this fix in ChromeOS. Jorge, can you please help with an owner.

Assigning to our toolchain team. Luis, can you route this one? I'll still double-check that our glibc is affected (but it probably is).

Yup, just checked, we don't have the patch in ChromeOs.
Am working on patching glibc.

keescook@ / jorgelo@ - Does ChromeOS use Milestone or Security Impact labels? I have a query that catches bugs that are missing these labels and wish to know whether I should dismiss any "OS-Chrome" bugs or harass you to add milestones and security impact labels where they are missing. Long sentence is long.
May 28, 2014
#11 jorg...@chromium.org
We should, but we haven't been exhaustive nor systematic when adding labels in the past. Harassing is better than dismissal.
May 28, 2014
#12 timwil...@chromium.org
Good to know.

yunlian@ - What milestones / versions are affected by this bug?
May 28, 2014
#13 yunl...@chromium.org
I think all the versions before this fix are affected.

#14 timwil...@chromium.org
Speculatively adding labels based on c#13 - feel free to change the severity as you see fit.

Removing M-35 label - this won't make that release.
