Detailsinfo

A vulnerability, which was classified as critical, has been found in Apple iOS up to 7.1 (Smartphone Operating System). Affected by this issue is an unknown code of the component WebKit. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in Apple Safari 7.0.2 allows remote attackers to execute arbitrary code and bypass a sandbox protection mechanism via unspecified vectors, as demonstrated by Liang Chen during a Pwn2Own competition at CanSecWest 2014.

The weakness was disclosed 04/22/2014 by Liang Chen with KeenTeam as HT6208 as confirmed advisory (Website) via Zero Day Initiative (ZDI). The advisory is shared for download at support.apple.com.

The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are unknown but a public exploit is available. The advisory points out:

Multiple memory corruption issues existed in WebKit.

The exploit is available at exploit-db.com. It is declared as proof-of-concept. As 0-day the estimated underground price was around $100k and more. The vulnerability scanner Nessus provides a plugin with the ID 73304 (Mac OS X : Apple Safari < 6.1.3 / 7.0.3 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 121875 (Apple Safari 6.1.3 / 7.0.3 Not Installed (HT6181)).

Upgrading to version 7.1.1 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

These issues were addressed through improved memory handling.
Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 13742.

The vulnerability is also documented in the databases at Exploit-DB (44204), Tenable (73304), SecurityFocus (BID 66242†), Secunia (SA58140†) and Vulnerability Center (SBV-57703†). The entries VDB-9457, VDB-11526, VDB-12548 and VDB-12549 are pretty similar. Once again VulDB remains the best source for vulnerability data.
