    VAR-201101-0025

    Vulnerability from variot - Updated: 2023-12-18 12:39

    lnsfw1.sys 6.0.2900.5512 in Look 'n' Stop Firewall 2.06p4 and 2.07 allows local users to cause a denial of service (crash) via a crafted 0x80000064 IOCTL request that triggers an assertion failure. NOTE: some of these details are obtained from third party information. Look 'n' Stop Firewall is prone to a local denial-of-service vulnerability. Local attackers can exploit this issue to cause the affected application to stop. Look 'n' Stop Firewall 2.06 and 2.07 are vulnerable; other versions may also be affected. ----------------------------------------------------------------------

    DESCRIPTION: A vulnerability has been discovered in Look 'n' Stop Firewall, which can be exploited by malicious, local users to cause a DoS (Denial of Service).

    The vulnerability is caused due to an error in the "lnsfw1.sys" driver when handling the 80000064h IOCTL. This can be exploited to cause an assertion error and crash the kernel via a specially crafted input buffer passed to the IOCTL.

    The vulnerability is confirmed in version 2.07. Other versions may also be affected.

    SOLUTION: Restrict access to trusted users only.
