Description:
A vulnerability has been reported in McAfee VirusScan Enterprise, which can be exploited by malicious people to cause a DoS or to potentially compromise a vulnerable system.
The vulnerability is caused due to an error within the On-Access scanner component when processing file names that contain multi-byte characters (e.g. Chinese). This can be exploited to stop the On-Access scan or to cause a heap-based buffer overflow via a file with a specially crafted, overly long filename.
Successful exploitation may allow execution of arbitrary code but requires that East-Asia language files are installed, the default Unicode codepage is set to a language that contains multi-byte characters, and that the attacker is able to place the specially crafted file on the target system.
The vulnerability reportedly affects versions 8.0i Patch 11 and prior.
Solution:
Apply Patch 12 or later.
