Discussion

International Components for Unicode Invalid Byte Sequence Handling Vulnerability

The International Components for Unicode is prone to an input-validation vulnerability because the library may incorrectly convert some invalid byte sequences.

An attacker may leverage this vulnerability to bypass content filters. This may lead to cross-site scripting attacks or allow the attacker to obtain sensitive information in some cases. Other attacks are also possible.

NOTE: This issue was previously covered in BID 34926 (Apple Mac OS X 2009-002 Multiple Security Vulnerabilities), but has been assigned its own record to better document it.
