Description Jan Lieskovsky 2011-10-18 13:47:27 UTC
A denial of service flaw was found in the way the bytecode engine of the Clam Antivirus scanner handled recursion level when scanning an unpacked file. If a local user was tricked into scanning a file or directory with 'load bytecode from the database' feature enabled, it could lead to clamscan executable crash.
