Common Vulnerabilities and Exposures assigned an identifier CVE-2014-1721 to
the following vulnerability:

Name: CVE-2014-1721
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-1721
Assigned: 20140129
Reference: http://googlechromereleases.blogspot.com/2014/04/stable-channel-update.html
Reference: https://code.google.com/p/chromium/issues/detail?id=350434
Reference: https://code.google.com/p/v8/source/detail?r=19834

Google V8, as used in Google Chrome before 34.0.1847.116, does not
properly implement lazy deoptimization, which allows remote attackers
to cause a denial of service (memory corruption) or possibly have
unspecified other impact via crafted JavaScript code, as demonstrated
by improper handling of a heap allocation of a number outside the
Small Integer (aka smi) range.

This is possibly impact moderate or low with the way v8 is used in Red Hat products and Fedora. Investigation ongoing.

Comment 1 Murray McAllister 2014-04-10 07:16:50 UTC
Created v8 tracking bugs for this issue:

Affects: fedora-all [bug 1086118]
Affects: epel-6 [bug 1086119]

Comment 2 Tomas Hoger 2014-06-16 14:18:17 UTC
Most of the patch is applicable to v8 3.14.  However, the test case form upstream commit does not reproduce any issue with 3.14.  It requires removal of %SetAllocationTimeout which is not supported in that version.  It does not seem such change should break the test.

Comment 3 Tomas Hoger 2014-09-04 14:03:43 UTC
Not reproducible with the other test case from the other bug:

https://code.google.com/p/chromium/issues/detail?id=350434#c12

Assuming this is not needed for 3.14.
