Input validation

Comodo Firewall Pro before 3.0 does not properly validate certain parameters to hooked System Service Descriptor Table SSDT functions, which allows local users to cause a denial of service system crash via 1 a crafted OBJECTATTRIBUTES structure in a call to the NtDeleteFile function, which leads ...

Code injection

Sophos Anti-Virus 7.0.5, and other 7.x versions, when Runtime Behavioural Analysis is enabled, allows local users to cause a denial of service reboot with the product disabled and possibly gain privileges via a zero value in a certain length field in the ObjectAttributes argument to the NtCreateK...

NULL pointer dereference triggered by ptrace

The Linux kernel 2.6.20 and 2.6.21 does not properly handle an invalid LDT segment selector in %cs the xcs field during ptrace single-step operations, which allows local users to cause a denial of service NULL dereference and OOPS via certain code that makes ptrace PTRACESETREGS and...

CVE-2007-4968

Privatefirewall 5.0.14.2 does not properly validate certain parameters to System Service Descriptor Table SSDT function handlers, which allows local users to cause a denial of service crash and possibly gain privileges via kernel SSDT hooks for 1 NtOpenProcess and 2 NtOpenThread...

CVE-2007-1194

Norman SandBox Analyzer does not use the proper range for Interrupt Descriptor Table IDT entries, which allows local users to determine that the local machine is an emulator, or a similar environment not based on a physical Intel processor, which allows attackers to produce malware that is more...
