** Description changed:
- The Ubuntu Error Tracker has been receiving reports about a problem regarding
gnome-software. This problem was most recently seen with package version
3.26.3-2ubuntu1, the problem page at
https://errors.ubuntu.com/problem/d94c431d27115bab216f9e1ea756f876e7cd933b
contains more details, including versions of packages affected, stacktrace or
traceback, and individual crash reports.
- If you do not have access to the Ubuntu Error Tracker and are a software
developer, you can request it at http://forms.canonical.com/reports/.
+ [Impact]
+ snapd-glib can do an invalid memory access when parsing HTTP chunked data.
Found doing code inspection and testing based on crash reports.
+
+ [Test Case]
+ No specific trigger - just look for reduced reports on errors.ubuntu.com.
+
+ [Regression Potential]
+ Some risk of further breaking HTTP handling in snapd-glib. Updated algorithm
tested in a test program run through valgrind to give confidence in the changes.
