OVERVIEW

        A number of vulnerabilities in SQLite affected Tenable Nessus and 
        Tenable Nessus Enterprise prior to versions 5.2.11 and 6.3.7. [1]


IMPACT

        The vendor has provided the following details regarding these 
        issues:
        
        "SQLite contains an off-by-one overflow condition in the 
        resolve_backslashes() function. The issue is triggered as 
        user-supplied input is not properly validated when handling .\ 
        commands. This may allow a remote attacker to cause a limited 
        heap-based buffer overflow, resulting in a denial of service or 
        potentially execution of arbitrary code.
        
        SQLite sqlite3VdbeExec() Function Database File Handling Heap Buffer
        Overflow:
        
        SQLite contains an overflow condition in the sqlite3VdbeExec() 
        function. The issue is triggered as user-supplied input is not 
        properly validated when handling database files. This may allow a 
        context-dependent attacker to cause a heap-based buffer overflow, 
        resulting in a denial of service or potentially allowing the 
        execution of arbitrary code.
        
        While Tenable has not confirmed this is exploitable, we have 
        upgraded the software to use the latest version of SQLite as a 
        precaution." [1]


MITIGATION

        It is recommended that users update to the latest versions of 
        Tenable Nessus and Tenable Nessus Enterprise to correct these 
        issues. [1]
