Hole in the system...
Member of the BSA, Symantec has patched a security hole which it found in its anti-virus software. The vulnerability exists in the Windows version of the Symantec Antivirus component which tests RAR files for viruses.
Symantec has said that the security consequences of the hole are small. All it does is cause the decomposer component to crash when a unique RAR file is received for decomposing and scanning.
However, technically malicious content placed inside such a configured RAR file to bypass the initial AV software scans. , This might work if the virus is picked up later by the RealTime Virus Scan / Auto-Protect function.
The vulnerability has been traced to a particular component build environment that was only used for a limited period, so it is uncertain how many versions of the software suffer from it.
