This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

WebKit, as used in Apple iOS before 5.1 and iTunes before 10.6, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than other WebKit CVEs listed in APPLE-SA-2012-03-07-1 and APPLE-SA-2012-03-07-2.

The weakness was shared 03/07/2012 by Martin Barbella (Slawomir Blazek) with Google Chrome Security Team as HT5190 as confirmed knowledge base article (Website). The advisory is shared for download at support.apple.com. The vendor cooperated in the coordination of the public release. This vulnerability is traded as CVE-2012-0621 since 01/12/2012. It is possible to launch the attack remotely. A authentication is needed for exploitation. Technical details are unknown but a private exploit is available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 01/11/2025). It is expected to see the exploit prices for this product increasing in the near future.

A private exploit has been developed by Martin Barbella. It is declared as proof-of-concept.
