DESCRIPTION:
A vulnerability has been reported in Sophos Anti-Virus, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service) or gain escalated privileges.
The vulnerability is caused due to an error in the
savonaccessfilter.sys driver when processing system call parameters.
This can be exploited to corrupt kernel memory and execute arbitrary
code in kernel space via specially crafted parameters passed to the
"NtQueryAttributesFile()" function.
SOLUTION:
Update to version 7.6.20 or later.
