[Bug 552287] [NEW] IcedTea6 1.8pre (6b18~pre3-0ubuntu1) buffer overflow, possible crasher

 

You have been subscribed to a public bug:

See Mozilla bug https://bugzilla.mozilla.org/show_bug.cgi?id=555342.

(Apologies for this report, I'm not the person who discovered this bug
and am relaying the discoverer's information.)

1) Ubuntu 10.04 b1
2) IcedTea6 1.8pre (6b18~pre3-0ubuntu1)
3) No buffer overflow
4) Buffer overflow

See the steps to reproduce in the Mozilla bug; the buffer overflow is
more dramatic in Firefox nightlies with out-of-process plugins because
it always results in a crash in the plugin subprocesses.  It will only
sometimes result in a crash of the Firefox process.

It's easier to just paste a fix for this bug than describe it more.  The
diff is against http://icedtea.classpath.org/hg/icedtea6 revision
911fc7449289.

Marking security vulnerability for safety; I think this would be hard to
exploit.

** Affects: openjdk-6 (Ubuntu)
     Importance: Undecided
